• SF strips offer maximum protection against sticking, discoloration, dust, and humidity. • Stamps held securely in place by strong clamp-type seal. • SF mounts are made from 100% polystyrene (free from softening agents, acids and stabilizing chemicals). • Anti-reflection coating prevents light interference. • Special adhesive on reverse side of film (simply moisten and affix). For most standard sizes. Please note: the size of the mount is cut 4 mm larger than the actual stamp for that nice “centered” look. The sizes listed represent the size of the stamp. You do not need to add extra salvage.
D = Doragard (closed top and bottom, open at back) d = double seal (closed top and bottom)
