I first bought some slimes for my little sister and I noticed the clay textured ones were very slimy. I got these pens for her so she wouldn’t have to mix the borax bc she’s 7 and likely to mess up. These pens are magical! They fixed all the slimes with that clay texture. The cloud texture slimes did not need the pen at all, they were perfect. I will say go easy on the sprays bc a little does go a long way. I found 1-2 sprays worked perfectly to get rid of any excess sliminess.
