"Seaweed" comes as a set of two stamps, measuring 3.8 x 0.4in and 2.8 x 0.5in Clean, clear, and easy to use, Lavinia Stamps are manufactured from high quality transparent resin, ready for mounting on clear acrylic stamping blocks, you can now clearly see through to exactly where you are stamping – so no more crooked images! The clear polymer resin used to manufacture these stamps enables them to cling onto the acrylic block without the need for adhesive. All Lavinia designs are supplied flat on a sheet of acetate and easily peel off ready for use. Once you have finished your project, simply peel your stamps off the acrylic blocks. A quick wash with soap and water, and they are ready to be popped back onto the acetate sheet for easy storage.
