Having Joel and Clementine from the film Eternal Sunshine of the Spotless Mind on the front of your fridge would be the coolest magnet ever. Especially if you used them to hold notes for shopping lists and other helpful reminders - stuff you want to remember. Ha.
These are small figurines with magnets on the back. Ideally they would be two separate characters, so you can detach them from each other if you’re feeling cruel.
You could probably get Rude & Reckless to make you a set.
