Review on Set of 5 Durable Large Retainer Cases with Ventilation Holes for Orthodontic Retainer, Invisalign, Mouth Guard, and Denture Storage - Tight Snap Lock, Color May Vary by Brian Benford

Although I did not receive the colors shown in the picture, it does not matter because they are ultimately very strong and practical storage containers. After my cat lost one of my Invisalign retainers that I forgot to put away, I realized I had to have multiple containers for her around the house. It worked great! A branded Invisalign case costs more than these 5, and for what purpose? These are cheaper, breathable, spacious and of good quality. I highly recommend adding bulging eyes to them because it makes them cute and even easier to spot for the absent-minded like me.
