We recently purchased a Billy bookshelf from IKEA, and added Oxberg doors to create a wonderful board game cabinet.

We also have a toddler.

Hence the IKEA Oxberg Latch

The rubber bands we were using before worked, but were tacky. Now we have an attractive solution.

It had not been fully toddler tested, so your mileage may vary. I'm also confident that our test subject will figure it out the first time he sees one of his older siblings open it.... We will see.
