This was my first time buying slime. I’ve heard it is a great sensory tool to help with anxiety. I decided to give it a try and as an adult I have to admit it was really fun. After a few days I noticed the texture changed a little, it got a little harder to play with and it deflated. I tried the directions on the little card, the borax solution and it changed for a day or two but a after a few days of using it again, the texture went back to what I noticed before. I still use it once in a while but is not as stretchy as it used to be. I guess I need to buy different textures to try next time.
