Invisible Multi-Functional Bed Sheet Holder New Anti-Slip Home Use Plastic Clips to Fix Bed Sheets Prevent Running And Sliding

took about a week to arrive. works as described even on my thin mattress and has the grip at the bottom as that the bed won't slide around. works well for the corners but not the middle of the bed. easy to install if your bedsheet is not the taut kind. will make the mattress abit bigger so it might not fit nicely into the bedframe.

not good
