This retainer holder has everything I didn’t even know I needed — the built-in mirror is super handy for checking aligners on the go, and the adjustable vent holes keep things fresh instead of trapping moisture. It fits my Invisalign (and other retainers/guards) perfectly and gives me peace of mind when I’m out and about. I also love that it comes with an aligner remover tool, chew, and brush — thoughtful extras that make daily care way easier. The case feels sturdy and well-made, and it’s compact enough to toss in my purse or gym bag without bulk. Great quality, practical design, and everything works exactly as advertised. Highly recommend! 😄 Review: Great Price - Great Product - After several months of use, the case has held up well. Performs exceptionally well when engaged in normal use like pockets, and purses. If dropped the clasps opens and releases items(as you would expect). The rubber lined bottom tray stops the shifting and the mirror is clear and remained in tact after the fall. This is a definite five if used as intended. ## Features - PORTABLE RETAINER CASE WITH MAGNETIC CLOSE - This travel retainer case is 3.15 in diameter × 1.1 in height, slim and lightweight. You can put this retainer holder in your purse, bag, lunch box and pocket. The magnetic closure keeps the case securely closed to ensure the safety of your aligner. - ENOUGH INTERIOR SPACE - We went through a lot of research before designing this aligner case to ensure it fits all aligner brands such as Invisalign. It can even accommodate retainer accessories such as an Invisalign remover tool, aligner chewies and Dental floss while storing your retainers. - PREMIUM MATERIAL - This nightguard case is made of food-grade ABS. Not only aligner, but you can also use this mouthguard case to store your wire retainer, partial denture, mouth guard, night guard and even your other small items. - USER-FRIENDLY DESIGN - Built-in mirror helps you easily put on and take off the retainer and check if food is stuck in your teeth. The food-grade silicone pad on the inside prevents the retainer from moving, protecting your holder and reducing rattling noise in pockets and purses. Package included: 1× black retainer case, 1× retainer remover tool, 1× retainer chewie, 1× retainer brush. - 4 VENT HOLES WITH SLIDING SWITCH - In order to coordinate the balance of ventilation and protection, we have specially designed 4 vent holes that can be freely opened and closed. You can close these vent holes to avoid dust contamination of your retainers or open them to fully ventilate your retainers. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B9RLH5C3 | | Best Sellers Rank | #21,685 in Health & Household ( See Top 100 in Health & Household ) #45 in Personal Orthodontic Supplies | | Customer Reviews | 4.7 4.7 out of 5 stars (1,649) | | Department | mens | | Manufacturer | Heigoeost | | Package Dimensions | 3.58 x 3.58 x 1.14 inches; 2.4 ounces | ## Images ![Heigoeost Slim Round Retainer Case (Black) - Image 1](https://m.media-amazon.com/images/I/71Lz5asJYpL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Purple and Pink!! *by C***A on January 15, 2026* Such a smart little case!

A Must have for Aligner Care! *by A***A on February 23, 2025* My high school daughter started Invisalign treatment and I bought this retainer case with a mirror for her. The added mirror is a fantastic feature. It’s incredibly useful for checking aligner and rubber bands fit. No more fumbling with mirrors in the car or at the office – it’s right there when you need it. The mirror is clear and easy to use, and it adds a level of convenience. It algo comes with a aligner remover tool, its easy to use and makes it easier to remove aligners and in my daughter’s case, rubber bands without having to stick her fingers inside her mouth all the time. Overall, this retainer case with a mirror is an excellent product, and I would highly recommend it to anyone who wears aligners regularly. It’s practical, well-designed, and makes aligner care much more convenient. ## Frequently Bought Together - Retainer Case, Slim Aligner Case with Adjustable Vent Holes and Mirror, Compatible with Invisalign, Night Guard and Mouth Guard, Premium Retainer Case, With Aligner Remover Tool, Chew & Brush, Black - Retainer Cleanser Tablets Invisalign Cleaner FSA HSA Approved Remove Odors Discoloration Stains and Plaque 4 Month Supply Denture Cleansers Retainers Mouth Guards Denture Bath Mint by M3 Naturals - Movemints Clear Aligner Mints - Patented, Edible Alternative to Chewies - Freshen Breath and Improve Dry Mouth with Xylitol - Spearmint (3 Pack) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/479602476-heigoeost-slim-round-retainer-case-black](https://www.desertcart.jp/products/479602476-heigoeost-slim-round-retainer-case-black) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-05-07*
