Perma make a lot of these sorts of products. There are fancier-looking solid latches, but in my experience, they are more trouble than they’re worth. These may not be pretty, but they are the most practical cupboard locks for children by far.

Poor quality product, adhesive comes out after few days despite following the instructions in terms of cleaning the surface and waited as instructed. Total waste of money I wish I give it zero rating

The idea for this simple product is great, however cheap materials are used. The base falls off after a few months and the straps break after a similar time. Gone through a few sets now.
