I came across this today thought it would be cheap little item to help. Make sure to read the comments one guy has a alternative idea that he put to work extending the storage space. Good Luck

Hm. Nice. It occurs to me that you could make them from the tops of mouthwash bottles, too. Probably not watertight, but slightly larger and baby-proof... would be good for storing pills in.

That is so awesome. To think of all these uses for items I considered as trash. Well, learned yet another new thing today. Thanks RuDown.

I reuse my wife's empty spice bottles and jars. Some about 1.5" long and 1.25" diameter and the sizes go up from there.
