Praise Rael.
Style: Bundle, Size: 2 Piece Set
I suffer from cystic acne (on my chin and jawline, so probably connected to hormones) as well as dematillomania, or skin picking disorder. It's so hard for me to not pop the big honkers, especially when these painful zits have been around for days/weeks. All I want is clear skin, but cystic acne combined with skin picking leaves me with scars that take months to fade even when I'm pimple-free . I've been using Rael's Miracle Patch (pink package) for awhile. This is a great product, and works best on more surface-level zits. Last night, I tried the Acne Healing Patch (green package) on a persistent cystic zit I've already tried to extract, plus another cyst brewing on the other side of my chin. I've used so many different products to treat cystic acne, but nothing has worked like Rael's Acne Healing Patch. I kept the patches on overnight, and in the morning I found both had reduced significantly in size. The zits are well on their way to healing, and I finally feel like I will be able to treat cystic blemishes effectively and go concealer-free in the coming months. I never write reviews, but I felt I should share this experience with Rael patches. Acne can be so mentally debilitating, and I've been helped by a lot of fellow acne sufferers who share their experiences in product reviews. I hope my review is helpful for someone else. Thank you Rael, for a truly game-changing cystic acne treatment!

Perfect toy for an active dog!
Color: Large size (7.9")
My dog absolutely loves this ball with handles! It’s quickly become one of his favorite toys, and he gets excited every time we bring it out to play. The vibrant colors are a huge plus—they make it super easy to spot in the grass, which saves a lot of time during outdoor play sessions. The handles are great for interactive play too, especially for tugging and tossing. I’m really impressed with how well it’s holding up. Even with constant pulling, tugging, and rough use, it’s remained durable and hasn’t shown any signs of wearing out. Overall, I’m very happy with this purchase—and if my dog could write reviews, it would definitely get his paw stamp of approval! 🐾

Great idea poor construction
Color: Large size (7.9"), Color: Large size (7.9")
Great for a dog that likes tug and fetch but the seams are not strong so it ripped fast not from tug but my dogs teeth. I sewed it once since we loved playing with it but it didnt last. Other seams opened. The seams opened in the ball part not by the handles. Less seams and stronger ones would make it 5 star. Im trying a different brand.
