Below you will find our customized, clear "Handmade By" stamps. Use these stamps to sign the back of greeting cards and other similar projects. You can even press into soft clay to easily sign sculptures. These stamps will work with most clear blocks. (Simply peel and stick.) So if you already own a block, there is no need to purchase another as long as the stamp will fit. If you need a stamp block, please click on the stamp block image below for stamps with blocks included. The stamps and blocks can be washed with regular dish soap.
