This is a 6 x 6 slightly curved acrylic block with a handle. It is made to make stamping large stamps easier and goes great with Impression Obsession's Cover-a-Card cling background stamps. Use it with all of your unmounted rubber and clear stamps. So easy to hold and use! Using traditional mounting methods, large stamps can be awkward to hold and difficult to get even pressure to all parts of the stamp. Impression Obsession's innovative acrylic stamp handle is a full 6 x 6 to handle nearly any size image. It features an easy-to-hold handle that you won't drop onto your paper accidentally. A slightly curved surface transfers pressure to only part of the stamp at a time, ensuring a crisp and clean impression every time. Use the Mega Mount with cling, clear, and Cover-a-Card background stamps or any other large stamps you have.
