Waste everyone's time, including your own, with this instantly unconvincing Fake Oyster Card sticker kit. Stick it over your real Oyster card so it looks like a fake Oyster card, even though it still works like a real Oyster card. There you have it. Why would you do this? Don't ask me. You bought it. From here remember: https://www.spellingmistakescostlives.com/product-page/fake-oyster-card-sticker-kit
Went back to acrylic paints for this one. Not sure why, but the idea of it has been making me laugh for weeks, so here it is. Hang it up in your break room at work.
You can have it as a cheap (£20+) limited edition print if you like from the shop.
