It is made of sturdy cardboard that is designed for storage and multiple uses.

After pre-drilling, there was no problem. X-protection furniture pads are just the right sized for my project. Chairs slide better and back to quite sliding.

The felt just rips off the mount and your floors are scratched. Terrible adhesive. The glue is cheap and will not stick to the pad.

These gliders are flimsy and small. They easily bend and a few actually snapped in half! Thin gauge nails result in bending when hammered into chair legs.

Make sure surface is cleaned with alcohol and dried prior to sticking it. My beautiful teak floors are now protected by new pads. They save my hardwood floor.

Also pas gets squeezed and becomes so thin. These are cheap trash. Very disappointed in this product for that reason.

The pads are nice, but the glue stays fresh and won't dry, so they will keep coming off defeating the purpose for which i ordered them. The sticky side just isn't sticky enough to stick to plastic or wooden legs of furniture.
