"Oyster Evening" travel card sticker (designed to be stuck onto top-up travel cards).
Made from a durable vinyl with a laminate that protects it from scratching, rain and sunlight.
Sticker measures 51mm x 82mm (relatively standard size for transit cards, so this sticker should fit on most travel cards of this kind), comes with a backing card explaining it's use, in a clear cellophane bag for protection.
NOTE: While I designed these specifically to stick to your travel card, it is still just a sticker, you can stick it to whatever you like! :)
