Clear stamps are known by different names. As well as being called acrylic stamps they may be called polymer stamps, photo-polymer stamps, clear rubber stamps or any variation on the above. They all fall under the heading, however, of 'clear stamps'.
When attached to a block, clear stamps can be used repeatedly in a similar manner to a traditional stamp. Clear stamps are readily available from rubber stamping and craft stores, as well as online
The features of clear stamps are:
· They are almost completely transparent when purchased.
· The stamps are slightly tacky allowing them to be adhered to a stamping block for use.
· They are stored on a backing sheet, in a protective wallet or container such as a CD case.
· Clear stamps are sold individually or on a sheet containing several stamps. http://www.china-crafts-supplies.com/clear-stamps/
