Kanematsu Usuba KnifeThe Usuba is a traditional Japanese vegetable knife designed for delicate tasks such as katsuramuki and decorative cutting. This Usuba knife uses Yasuki steel.
The dark portion of the blade has been treated with a black oxide finish. This finish forms a stable oxidized layer on the iron surface, helping to suppress red rust while giving the blade a calm black appearance. The contrast between the rugged black blade surface and the polished silver edge creates a strong presence as a tool. With continued use, the appearance of the blackened area will gradually change, which is one of the unique charms of carbon steel knives. Since the black finish was not applied to a brand-new blade, the color may appear uneven in places, which can also be appreciated as part of its character.
This knife is single-edged and made of carbon steel, offering excellent sharpness.
Professionally sharpened and ready to use. Sharpening service is included in the price. Please handle with care when unpacking.

Quick and easy to apply, plus NO white cast on brown skin!
Style: Face, Size: 2 Fl Oz (Pack of 1), Style: Face, Size: 2 Fl Oz (Pack of 1)
Admittedly, I don't normally wear sunscreen (maybe for a rare day at the beach, but certainly not on a daily basis). However, upon getting my first tattoo, I learned that the sun is a tattoo's mortal enemy, so I did a ton of research on sunscreens to find a good brand that would be effective in preventing the premature fading of my ink (gotta protect my investment, y'know?). Many people recommend mineral sunscreen instead of chemical for tattoos, and since I'm Black / brown / African American, my main concern was choosing a product that wouldn't leave a white cast. After reading the reviews of countless products, I finally settled on trying Thrive (the SPF 30 Face Sunscreen), and after two months of using this product, I can confidently say I hit the jackpot on the first try.
The consistency of this sunscreen is creamy (similar to that of a standard lotion), so it spreads very easily and is "absorbed" into/onto the skin within seconds. And the best part is, there is absolutely NO white cast -- I've attached photos of both my tattooed and non-tattooed forearms post-sunscreen application for reference. You can see that there a little shine on my tattoo (which I actually like), but otherwise no discoloration from the product. In hindsight I probably should have taken before-and-after photos for both arms, but just take my word for it: there's seriously no cast. Also, the product has a slight smell (kind of citrusy, like grapefruit), but it's not strong nor unpleasant and it doesn't linger. After being rubbed in, the product feels a little sticky as it dries, but it dries pretty quickly and then leaves the skin feeling smooth/normal.
The only semi-con I have is that after applying and reapplying multiple times in a single day (like 3+ times), I've noticed some slight white flakiness (I'm thinking this is just product build-up, since the minerals in this sunscreen sit on top of your skin as opposed to being fully absorbed). However, this is not really a big deal to me, as the flakes can be wiped away, but if it were really noticeable or if I knew I would need to continue reapplying that day, I could probably just wash my arm off real quick with some soap and water, then dry and reapply to resolve the problem.
As a final note, I'm not actually sure if this sunscreen is effective in providing sun protection. I don't get sunburnt, so I don't really have any way of knowing whether this product is fulfilling its intended purpose (I guess time will tell; for now I'll just keep an eye out for my ink fading). But assuming it is in fact working, I 100% recommend this product!

Amazing Pimple Patches - Actually Work!
Size: 36 Count (Pack of 1)
Effectiveness: These Mighty Patch Original hydrocolloid patches have been absolutely incredible for treating breakouts quickly and effectively without harsh chemicals or painful extraction. The patches work remarkably well overnight, drawing out impurities and reducing the size and inflammation of pimples by morning. I love how they protect blemishes from picking and touching, which prevents further irritation and scarring. The clear design makes them virtually invisible during wear, so I can use them during the day without feeling self-conscious. The patches stick securely without being painful to remove, and they genuinely speed up the healing process compared to leaving breakouts untreated.
Quality: Hero Cosmetics has created an exceptional product with these hydrocolloid patches that clearly demonstrates superior manufacturing quality. The adhesive is perfectly balanced - strong enough to stay in place through sleep and daily activities but gentle enough to remove without skin irritation. The hydrocolloid material is high-grade and effectively draws out fluid and impurities without over-drying the surrounding skin. The patches maintain their integrity throughout wear and don't fall apart or lose effectiveness. The sterile packaging ensures product safety and hygiene, which is essential for treating open or inflamed skin.
Value for Money: These pimple patches provide outstanding value when you consider how effectively they treat breakouts while preventing scarring and further damage from picking. The cost per patch is reasonable considering the dramatic results they deliver, often clearing blemishes faster than expensive acne treatments. The prevention of scarring alone makes these worth far more than their price, as treating acne scars is much more expensive and time-consuming than preventing them. The convenience and effectiveness make these far more cost-effective than multiple skincare products or dermatologist visits for individual breakouts.
These patches have become essential in my skincare routine and consistently deliver impressive results. Highly recommend for anyone dealing with occasional or persistent breakouts who wants fast, effective treatment!

The best patches!
Size: 36 Count (Pack of 1)
These work amazingly well! I just stick one on before bed and by morning the pimple is noticeably flatter and less red. It really does what it says without any picking or irritation.
They stay on all night even if I toss and turn, which I was surprised by, and they don’t feel uncomfortable at all while sleeping. I also like that they’re thin and kind of blend into the skin, so you don’t really notice them if you wear them during the day either. Super simple, effective, and way less stressful than dealing with breakouts the usual way. They fit well and the size is great, really absorbs all the yuck from a pimple. A great value for money!

Works Overnight—A Must‑Have for Surprise Breakouts
Size: 36 Count (Pack of 1)
I’ve tried a lot of pimple patches over the years, and the Mighty Patch Original truly lives up to the hype. These patches are incredibly easy to use and work best overnight—just apply to clean, dry skin and let them do their thing.
By morning, whiteheads are noticeably smaller (sometimes completely gone), redness is reduced, and the gunk is visibly absorbed into the patch. I love that they’re thin, clear, and stay put all night without irritation. They also prevent me from touching or picking at my skin, which is a huge bonus.
The 36-count pack is a great value, and I always keep these on hand for surprise breakouts before an important day. Simple, effective, and gentle—this is one skincare product I consistently repurchase. Highly recommend!

Love this product but not the best for stubborn pimples
Size: 36 Count (Pack of 1)
The Mighty Patch Original Patch from Hero Cosmetics is hands-down one of the best acne solutions I’ve used. These hydrocolloid stickers actually shrink pimples and whiteheads overnight — I wake up and see a noticeable difference, even on stubborn spots that usually take days to calm down.
They’re super easy to use — just stick on before bed and let them work while you sleep. They stay put, even if you accidentally touch your face, and don’t irritate my skin. I also like that they’re practically invisible enough to wear during the day if needed.
Great for emergency breakouts or everyday maintenance. For anyone who wants fast, gentle, mess-free results, these Mighty Patches deliver!
