With the specific tins I used the lids slid on, but were a fairly snug fit. I actually had some tins with fine spices like cinnamon that became harder to open because of the dust in the joint. Overall, if the lids are fairly snug, you should be all good.

Not at the time I created this nor for the cost I was looking for. There are a few other options available today that would make this project easier.

That's an awesome idea! You should post a picture!

Very nice! Thanks for the tip on the other battery holders!

That's a cool tip. I worry I'd forget them and end up with a dryer full of safety pins ;)

This works for some applications. However, it's very hard to grind cinnamon to the flour-like consistency of ground cinnamon at home. To do that you need a very high end grinder.
