Small Foam Table Corner Protectors for Baby, Pre-Applied 3M Tape, 12 Pack, Brown

What is the actual size (length x depth) of the protector - large and small? Description only provides package size.

Can you purchase more tape for these

Can these be removed without damaging table?

Can these be cut to fit? My bed frame base board sticks out and is only about two inches wide but I need corners on both sides to be protected.
