Mounts & Hinges
Mounts are clear sleeves that protect both the front and back of the stamp. They cost more than hinges but are worth it for preservation and presentation.
Hinges are tiny bits of gummed paper that attach stamps directly to album pages. They're affordable and easy to use, but they leave a mark. You may choose not to use them on mint stamps you want to keep pristine.
Many collectors use both, depending on the album page they are building. Want more information on how to use hinges and mounts? Click here.
