Simply the best and safest mount for your stamps. 

• 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.
