These are non-slip mats for bathtubs with suction cups. There are 3 out of 5 mats. They have been opened, but only unused items are being sold. I used 2 of them and found them very useful. (This is my personal opinion.) When my baby was in the baby bath, their bottom tended to slip and be unstable, so I used one mat. When they were learning to stand, they almost slipped in the bathtub and became scared of bath time, so I used them. After that, they seemed to like bath time and would get in the bath. When they could stand on their own, they would stick them to the bathtub walls and play with them. When shipping, I will remove them from the case and send only the 3 fish-shaped non-slip mats and the instruction sheet. (Please let me know if you do not need the instruction sheet.) ★Please check my profile before purchasing.
