I found it in a store and bought one, but because it was so easy to use, I bought two more when I bought other products online. I used it in all of my cupboards, and when I put it on the shelves in my fridge at the end, it fitted perfectly everywhere! Because it has a line on it, you can fold it straight to the length you want and cut it, so it won't bend and it's very neat. At first the smell is a bit of a concern, but if you leave the cupboard door open, the smell goes away after a few hours. The fridge hardly smells at all to begin with. It's a great product, and I'm sure I'll be buying it again.
