BGM Clear Stamp Acrylic Block - Grid is meant to be used with BGM Clear Stamp. The clear stamps are a versatile alternative to the traditional opaque rubber stamps we are used to seeing. To use, peel off the individual stamp from the sheet, place them anywhere on this acrylic block, and use them just like a regular stamp. You can arrange multiple stamps on the block in whatever design and combination you find pleasing and since the block and stamps are clear and gridded, the stamp can be very precise. For example, you can stamp on the corner of the paper, creating a border or use the stamp to decorate an existing picture or illustration without fear of misalignment or stamping over the edge. Because the stamps are made of a soft silicone-like material instead of the traditional rigid rubber, they can be very detailed and do not require too much pressure to achieve beautiful results. Each stamp sheet comes with multiple stamps, and they are easy to carry around.
