These are individual water resistant vinyl stickers of the Fathoms Free Cormorant logo. Great for sticker on cars, lunch boxes, cylinders or most other surfaces really.
 
They are 80mm (8 cm or just over 3 inches) in diameter and are easily peeled off of the backing paper. 
 
Postage for one sticker is sadly expensive due to the prices the Royal Mail now charge for postage, however up to 10 stickers can be shipped for the same postage cost, or stickers combined with other items to save postage.
