Lighthouse Black SF Mounts

The Mounts that I sell are made in Germany, 100% polystyrene, free from softening agents, acids and stabilizing chemicals.
The height of the mount is from inside the glue joint at the bottom to 2mm from the top, the 2 mm extra at the top is to make sure your stamp is adequately protected. So a 30mm mount is actually 32mm from inside the glue joint to the top.
