BOOMIBOO Retainer Case with Vent Holes, 4 Pcs Denture Case, Durable & Similar Mouth Guard Case for Black, White, Yellow and Blue - Tight Snap Lock, Easy to Use

Fits my clear aligners, chewy, and aligner puller perfectly. Very sturdy, and the closure is secure while still being easy to open. I like the air holes so moisture doesn't get trapped. Went through the dishwasher with no problem. Overall no complaints at all. A great little retainer case.

These are great because they have ventilation. I keep one in my purse, one on my nightstand, one at my desk... NEVER wrap your retainer in a napkin. That's how they end up in the trash.

My son wanted extra retainer cases to keep in my purse and in his backpack. These have held up well, but I think they probably cost about 3 cents each to make, so they're probably overpriced. That said, they have not broken and we do use them, so I would recommend them. It might not hurt to just ask your orthodontist for an extra case, though.

I bought the pack of four, and one came broken. I really only wanted one or two, so I’m not upset about it, but thought I’d warn others who may need them all. Other than that, they seem sturdy and can even be hard to open, which is not necessarily a negative in my book. I would order again.

I was going to use these as a container for my night mouth guard. I use denture antibacterial cleaner, and unfortunately I cant use with these containers because of the ventilation holes on the top AND bottom. I thought they would only be on the top, and thats why I bought them. The liquid cleaner would for sure leak right through. Hopefully I can return these.
