# MM643 - 215x44mm 15 Horizontal Strip Black Split-Back Mounts
The correct mount size depends on the height of your stamp. For example, a stamp measuring 36 millimeters in height requires a 41-millimeter mount. We’ve added a small extra margin of space to protect your stamps. If your stamp falls between two sizes, select the larger sized mount. You can also measure in inches, round your measurement to the nearest 1/16th of an inch, and match it to the nearest mount size.
Take a look at Mystic's Discovery Center for our guide on how to measure stamps for mounts.
Single precut mounts are the easiest to use because there is no cutting. However, if no precut mount exists for the width of your particular stamps, you may need to buy strip mounts. Strips can be cheaper than single mounts and are useful for stamps of different widths with the same height. Cutting is easy using a device known as a “guillotine.” See here to learn more about the Schneider G – Large Mount Cutter.
Photo cutters, which are available at Staples, can also be used to cut mounts. Cutting mounts with scissors doesn’t work well because mounts are too slippery!
To insert your stamp in a split-back mount, locate the split on the black background side. Lift a flap and gently slide the stamp in face-down. Then lift the other flap and lay the stamp flat inside. Close both flaps over the back of the stamp. Make sure the stamp fits smoothly inside. Lightly moisten the adhesive on the top of the back of the mount and press it firmly onto your album page.
To fully protect your stamps, we recommend applying stamps and mounts to only one side of your album page. Mounts placed on facing pages may tangle, while mounted stamps placed front and back can weaken the page.
Mystic Mounts are archival-quality, which means they’re made of the same material museums use to protect their philatelic items. Because they’re archival-quality, our mounts are acid free and contain no additives or softening agents. Plus Mystic Mounts don’t shrink or discolor over time – giving you years of service for pennies apiece!
