We get how important it is to have proper ventilation for your mouthguard, night guard, retainer or denture. That's why we include ventilation holes on the top of your cases so that everything air dries and is fresh the next time you use it Because a retainer case with vent holes is kinda a big deal. DUR-A-BLE FOR HAULING AROUND WITH YOU: we think quality is super important for your retainer case. While there are a lot of cheaply made retainer cases on the market that break just by looking at them, Fresh Knight uses plastic that is up to 50% thicker than the market standard. This means peace of mind that you can thrown this thing around, from your backpack or purse, to your gym bag and back home. Easy peasy...you have better things to worry about.

Right here in America baby. 2 PACK= NO WORRIES IF YOU LOSE ONE: With retainers and mouthguards, nothing is worse than losing your case and having to put it directly in your bookbag, gym bag or a plastic baggie (ewwwwww!) You get 2 sturdy cases, one for your bedside or bathroom at home and another for your bag on the go. Perfect as a holder for any of your other dental devices (mouth guard case, retainer holder, aligner case, night guard case). Each case measures 3"x3"x1.5"high.
