Beautiful Crate and Barrel glass photo coaster set! These are solid square glass mini frames. The set has 4 frames. The square is approx. 3.5 × 3.5 and it holds photos that are 2 × 2.75. Photos slide into a clear plastic cover and then into a slot on side of the frame. I only used them lightly for a birthday. They are in very good condition with only light wear. These are very versatile coasters that may also be used like paper weights etc. All offers considered.
