***Please read whole review for full story. Product is good. Delivery was issue.
Color: Light Rose Gold Body Glow, Color: Light Rose Gold Body Glow
I had ordered a bunch of items at once; but within the large box they came in that had no signs of forced entry, there were 2 boxes that were clearly busted open and tampered with, and unfortunately the body shimmer oil was one of them. You can see that someone opened it, and had to go through the plastic to do so, and this makes it concerning for health/safety issues when ultimately using the product. (Speaking in terms of people putting fentanyl on everything). Thankfully I don’t think that’s the case, and the body shimmer oil works as described. I have fair skin and personally I think the shimmer itself isn’t overwhelming or underwhelming- it’s just right. My only issue is that I’m sensitive to perfumes and I find the scent disturbs my respiratory system a bit, making me cough. If that’s not an issue for you, this is a good product.

Bouncy, not hard, and good value.
Style: Fetch Balls (Pack of 10), Size: 2.5 inch
Great balls for the ball launcher and not rockhard like some of the solid rubber balls. These have great bounce, and because of the two holes, they make a fun whistling noise as they fly through the air. My dogs love them and they are a good value. By the way, if you throw them too hard, they will go through chain-link and no climb fence because they squish a bit!
