Read the reviews.... These foam corners cost pennies to make and this outfit is charging a price as if they were made of wood or another durable product. This small business will stay a small business if they keep ripping off customers!

Not what I expected. Flimsy, Styrofoam, and does not fit correctly to corners.

Ya’ll I just paid $28 for styrofoam, not wood blocks. Very deceptive in my opinion since one would think “blocks” is made out of wood. Most crown molding is made out of wood or strong composite. Why would anyone want these delicate little styrofoam blocks to jam in between 2 boards. 🤦🏻♀️

What I received looks a little longer and thinner than what’s in the picture but they’re well made and worked perfect for my room.

Used these to rehab a bathroom ceiling with popcorn texture falling off. These were very easy to work with. Use a utility knife to trim to size. They are easily damaged, so handle with care. Use the Loctite adhesive recommended. Do NOT use liquid nails; it is thinner and does not dry white.
