Slime Advent Calendar 2026 - 24 days of non-sticky Christmas slime and charms

Slime Advent Calendar: the calendar that never gets stuck anywhere

Most parents have banned slime at least once. It sticks to the table, the carpet, and the dog. With this calendar, it’s allowed again. Behind the 24 doors are 12 Christmas slimes with their own names, such as Gingerbread Forest, Candy Cane Twist, Frozen Magic, Pinky Snowball, Christmas Mocha, and more, with 12 days of charms, sprinkles, and toppings to mix in between. The slime isn’t sticky, has a light scent, and comes in its own little tub with a lid, so it stays in the tub and doesn’t end up on your floor.

Slime today, charms tomorrow

One day, a tub of slime; the next, matching charms and sprinkles. This rhythm keeps a child opening doors until Christmas Eve, instead of losing interest by the 5th. Each slime has a different texture, such as butter, cloud, clear, and glossy, and its own scent.

Who is it for?

Children aged 6 to 13 who love slime, and the parents who don’t. It’s also for grandparents looking for something that isn’t chocolate, and older kids who say they’re too old for an advent calendar until they open door number one.

How it works

The calendar arrives ready to use in its own box. Open door number one on December 1, then open another door each day until Christmas Eve. Put the slime back in its tub, put the lid on, and you’re done.
