Custom "stamps" made with relief print using Speedball Speedy Carve or linoleum print blocks. Size can be up to 1 foot wide, 1 foot high. Prices vary based on size and complexity of design. Each print is cut out and attached to natural wood slice or wood block of your choice. Each stamp comes with a Ranger Archival ink pad, which is permanent, waterproof, doesn't smudge, and dries almost instantly.
Prints can also be commissioned and purchased as a print, not as a stamp (see last 4 photos as example)
