These are very fun and were easy to apply with a strong adhesive. They're textured which surprised me because I wasn't expecting that when I took them out. My daughter tries to attack them in the bath. She loves her bubbles but if I leave the water clear she can see these and just goes crazy. She likes the textured surface of them too. It could be compared to sandpaper, maybe 200 grit.
There's ten stickers total which really helped her to stop sliding around. That in itself was worth buying these. Just be sure to wipe down the surface really well before you try and stick these or they will come back up; however, if you have that issue like I did they are still pretty sticky and easy to reapply. .
