Item Description

This sleek retainer case is a nice "in between" size which fits most orthodontic appliances and Invisalign-type aligner trays. Click on the photo above to see the color chart (in "Additional Product Views").

This case includes a built-in key holder for expander/appliance keys. It measures 3" x 3" x 1", with 2.75" x 2.5" x .5" of usable inside space.

This retainer case snaps securely shut, and includes a hole for attaching our KeyChain Retainer Clip. Comes in a variety of solid colors, with a label on the bottom to help prevent loss.

Measure your retainer to ensure it will fit before you buy. Retainer cases cannot be returned due to health regulations.

Gift for my granddaughter
September 5, 2021
Apparently, my granddaughter loses her retainer case often, and she had only one left when she visited recently. So, I ordered several as a gift and had them delivered to her home, which is a couple hours away. I assume that she likes them, because itís the only kind Iíve ever seen her use.
  • The price is right, and, according to my granddaughter, they offer good protection for her retainer.

A great value. Loved the choice of colors. The case is sturdy. The product arrived on time.
  • Color choice
  • Sturdy construction
  • Price

Worked very well for my daughter's retainers
July 19, 2016
I really like this retainer case and didn't have any of the issues that the other reviewers mentioned. It's roomy and has a hole where I attached a clip. My daughter clipped it to the inside of her backpack. It stays closed well and her retainers fit well. There is even room for a couple of retainer wipes, which I also bought here. No complaints. Highly recommend!
  • Roomy and convenient. Opens and closes easily.
  • None that I can think of. Wish I could have found it locally, but glad that I found it here!

Too small for my son's bionator
April 15, 2016
Wow! Way too small. I ordered two which cost $8 and paid $7 to ship to find this out. Sad.
Merchant Response:We are sorry to hear that your son's Bionator didn't fit in the retainer cases you ordered. That is why we give the dimensions of the cases and tell customers to measure their dental appliance. Unfortunately, retainer cases are not returnable due to health regulations.
  • None.
  • Too small

Breaks easily when dropped
January 3, 2016
I drop these a lot. While they stay locked, they crack, and then break in half, easily when dropped.
  • They don't open up, even when they crack into two pieces. Also, I like the label for contact information. It gives peace of mind during travel.
