Know your Stamp Mount

Showgard Mounts are made of oriented polystyrene, that is to say, containing no softening agent that might be harmful to postage stamp ink, paper, or gum. The material does not shrink or discolor and is 100% waterproof.

Showgard Mount foil has had philatelic application for more than 50 years in every climate of the world. It is proven perfectly safe for stamps.

In addition to the time proven safety of the mount foil there is also the functional design of Showgard Mounts, twin parallel welds that keep stamps securely in position while permitting free passage of air around the stamp. 

Showgard Mounts are soluble in carbon tetrachloride or other hydrocarbons. Fortunately, these compounds have been replaced by environmentally safer fluids in watermark detecting.

Showgard Mounts have earned national recognition as the most favored stamp protection in the U.S.A. There is no other mount like it.

Simple as 1-2-3  Note: Showgard Mounts are pre-gummed on the entire back. 

1) Moisten top half lightly. The bottom half remains free. 
2) Turn stamp over in direction of arrow.
3) Place stamp into the free half as far as it will go. Allow mount to flap back into place. The stamp is now securely centered but can be removed without damage to stamp or mount.
