Royal Products Square Plastic caps Glide Insert Pipe Tubing End Cap Plastic Durable Chair Glide for Chair Table Stool Leg Pipe Inner Cap (35 * 35mm /3.5 * 3.5cm, 20)

The product was nicely packed and the build quality of the pieces are very good. I purchased these end caps for my 1.5 inches square tube, the sides needs to be trimmed to fit these into the tubes

Had ordered but received more than what i expected nice quality

Does not fit on 40x40

Ribs on plastic could be little softer so that it can be inserted in to tube without ribs getting damage.
