A biscuit tin will work just as well.
Wow I have a Christmas cookie tin thst I keep putting back on a shelf in my garage. My garage is so organized I hate clutter and everytime I go to throw it away I end up saying maybe I’ll use it as a container for big bolts or something . Thank you for letting me know !!
