Pleasantly Surprised!
Color: Grey Striped, Size: 72"W x 72"L (Pack of 1)
I was looking for this exact product but didn’t know it! We recently moved into a new home and had zero window treatments so needless to say I wanted something quick, affordable and not vinyl WalMart blinds. We are happy with our purchase and would highly recommend to others. Some complain of the adhesive not sticking- make sure to clean the window wells/walls etc prior to installing these. If the surface is free of dirt/grease there will be no issues with them staying put.

great quality pickle ball set of two
I really love the look of this pickleball set. The blue color and overall design look very stylish and premium. The quality feels great, and the portable carry bag makes the whole set even more convenient. I especially like that it comes with a bag because it makes it easy to store everything and carry it to the court. It also makes this set a great gift option for any pickleball lover.
This set includes two blue pickleball paddles along with balls and a convenient carry bag to keep everything organized. Since it comes with two paddles, it is perfect for playing a quick game with a friend or practicing together. It works well for both indoor and outdoor courts.
The paddles feel very well made. They are constructed with fiberglass, which makes them lightweight yet durable. Each paddle is around 8 oz, so they are easy to handle and comfortable even during longer games. The 13 mm polypropylene honeycomb core provides a nice balance of power and control while also helping reduce noise and vibrations when hitting the ball.
Another feature I really appreciate is the TPU edge protection. It helps protect the paddles from accidental drops and everyday wear and tear, which is especially useful if kids are also using them. The grip is another highlight. It has a cushioned and textured design that feels very comfortable in the hand. The breathable grip helps absorb sweat and prevents slipping, so you can play for longer periods without discomfort. The handle width also feels ergonomic and easy to hold, making it suitable for extended play.
The included carry bag is very practical. It easily fits the paddles and balls, and there is still room to add small items like a towel, water bottle, phone, or keys. It is comfortable to carry and makes transporting the set very easy.
Overall, I find this pickleball paddle set to be stylish, durable, and well designed. The quality feels great and it is perfect for beginners as well as casual players. I would definitely recommend it, and it also makes a thoughtful gift for anyone who enjoys pickleball.

I have much more expensive paddles but my wife has her best games while using these.
This paddle set comes with 2 paddles, 2 indoor balls, 2 outdoor balls, 2 extra grip tapes, and a bag large enough to fit all of these and small items like keys, wallet, etc. There’s a front zipper pocket, that I can put most of my accessories in. Then the larger main cavity that holds the paddles and everything else is also zipper operated.
Now let’s talk paddles. These are 13mm width paddles. They’re very lightweight, making the flickability a lot easier vs other heavier paddles. The paddles weigh only 7.1oz. The surface is fiberglass and is frosted. Allowing for some grip to assist with adding a topspin or slice to the ball. Since this is 13mm you can feel a bit of dwell time, although it’s not as much as the 16mm paddles. The feed back and response of the paddles are excellent. They produce a loud pop as the paddles makes contact with the ball. The grip tape on the paddles as they arrived as well as the extra grip tape is absolutely premium. They are sweat wicking, ribbed and is very grippy. This is great for some heated matches. Your paddles will not slip easily.
This is a great entry set to pickleball for the family without reducing quality and at a great price. I’ve played against my cousins and they have about a year of pickleball under their belt over me and I can beat them with their $200 paddles with these. That says very little but consider this set as an excellent quality stepping stone.
