Brilliant little invention. Well done!
I can’t describe how good this product is, this has helped my skin incredibly, rather then itching and damage my skin I can freely relieve the sensation of it!
I'm so impressed, it's saving my skin from being scratched red raw. The itching is worse at night so I keep it by my bed, it's cooling and soothing and stops the itched fast. My husband used it too and is very impressed
I have a really bad patch of eczema on my ankle. I bought a scratch star which is wonderful although sometimes can be a little difficult to use on my ankle so when the puffer itch roller came out I wanted to try it to see if it would be better with it being smaller.
It absolutely is!!! And the bumpy ball as an addition is and absolute god send. Because they're smaller I'm able to get in to the areas that I found difficult with the scratch star.
Well worth the purchase.
Amazing product, has really helped my daughter
Love this beyond words, not only is it nice and cooling, but the relief from being able to scratch safely and not break the skin is truly incredible. Thank you!
I’ve only had the star a few days, but I can see and feel the difference already. My eczema has calmed down considerably. The star allows me to relieve the itch without destroying my skin. Wish I had this years ago….
Perfect travel size or to fit into my handbag. Arrived super quickly and is so effective. It’s very cooling and gives a lot of relief.
Having the case is such a must honestly I love to bring my scratch star everywhere but I couldn’t without the dar because it would get dirty but now I take it EVERYWHERE and it’s so convenient love it !!!
I bought this for my boyfriend who's had eczema his whole life, tried many different products and none of them seemed to work until he tried this! Might seem expensive at first but you really get what you pay for.
I am diabetic so get awful itchiness in my legs. They're scarred and bleeding, but this star has helped immensely. It is totally perfect - feels nearly as good as fingernails and really convenient to use.
I have really bad eczema so I ordered this and the Puffer Itch Roller. One day after they arrived I cut my finger quite badly and required stitches. My stitches have been really irritating so I have used the Bumpy Ball to safely scratch them without causing damage to the stitches or further damage to my cut. This is super amazing. I cannot recommend the Bumpy Ball enough, or the Puffer Itch Roller.
I know this is a review for the Bumpy Ball but I will say that I have some other Cosi Care products and I highly rate them too. You cannot go wrong buying anything from this brand!
Lauren and her team took better care of me in the thick of TSW withdrawal than my medical team, such an amazing invention with love and thought poured into it (and every other product they have). If you’re on the fence get one!! Worth every penny and some! (So much so I had my mom buy them in the uk and send it to me now that I live abroad!)
Handbag friendly and great for my face and eyes - especially now it's spring and allergies are kicking in
What a fantastic product. Bought for my daughter who is always scratching her excema. She says this is soo relieving but without damaging the skin.
I bought it for my adult son who has eczema. He seems to like it and uses it a lot.

Can I use them with a moisturiser ?

The Scratch Star needs to be used with a moisturiser for added safety and glide on skin. If you do not use moisturiser or are doing NMT (no moisture treatment) the Scratch Attack Roller and the Puffer Itch Roller is the perfect product for you, as you do not need to use these devices in combination with a moisturiser
