Plastic case for mask?

Does anyone know where I can get a plastic case for my mask? I’ve had my mask for about 10 years and I want to keep it from getting dusty, so I’d just like a simple plastic case. I can’t really find anything online. If anyone has any suggestions, please let me know!

Tom Spina Designs. More than others but it’s nice.

Thank you both for the suggestions!

Both suggestions are great. The containerstore is a bit pricy but the quality is great! I don’t remember exactly where I got mine. It has a black base and the plastic kind of just connects into it with a separate plastic lid. I will look to see if I have any details on it
