All of my clear stamps are 100% handmade/homemade by me in my kitchen. No outsourcing ever. My clear stamps are like the clear stamps you buy on the mass market. They can be inked up the same way and stamp beautifully on paper, fabric or wherever you wish to stamp ink. They also work perfectly to impress texture into clay (polymer clay, paper clay, precious metal clay, etc). Stamps are flexible and unmounted so they work great on curved surfaces. Like any type of stamp, you should always clean your stamps after use and before storing them away. I DO NOT Recommend using solvent based inks (like Staz-on). It's very hard to clean off the stamps and over time the solvent reacts to the clear polymer structure and weakens it. The clear plastic backing can be removed if you wish to mount it to an acrylic block. I recommend leaving the plastic backing sheet on unless you are going to mount the stamp. It is VERY sticky underneath. Stamp size is approx. 2 3/4" X 4" before trimming away the excess background. Stamps with multiple designs can be cut apart with scissors. The etching is a little over a 1/16" deep, though they may be shallower in the more intricate areas of the stamp. Water is recommended to use as a release agent for stamping on clay. Stamps are made to order, so please allow 4 -6 business days for me to get them made and in the mail.
