Description 12mm diameter round stamp. This stamp is very small, designed for loyalty cards and therefore detailed images and fine text are NOT suitable. This product is NOT suitable for bitmoji images, as they are too detailed for this stamp size.  Check out our new bitmoji stamp instead! Pre-inked stamp requiring no messy ink pads, and lasting hundreds of impressions. Fully customisable with your own text above and below the image. Choose your own font from our extensive selection. Choose from our range of ink colours.
