OverMats consist of two pieces, one rigid
4-ply mat board and a paper backing sheet with ReTac™ adhesive on
one side. This gives them a finished appearance, both front and
back, without using two boards, so nearly twice as many will fit in the
portfolio. ReTac repositionable adhesive holds everything in place
until it is time to reorganize the presentation. The adhesive lasts indefinitely
but never becomes permanent. It's quick and easy to load, or to
change sleeved transparencies with no damage to image or mount.
OverMats fit in standard photo sleeves.
