4 x 4 frames are 1.5 times larger than their smaller 3 x 3 counterparts and make it much easier to find the perfect picture that fits. Simply trim 2 inches from a standard 4 x 6 print. Engraved and cut from our beautiful 1/8" frosted acrylic, they may be customized if desired by coloring the engraved area with paints, dyes, chalks, or pens.
