2 in 1 Outie Tool Aligner Remover for Invisible Braces | Easily and Safely Removes Top & Bottom Trays | 60 Count (Individually Wrapped Neon Green and Sky Blue Bulk)

The shape makes them perfect for getting invisiligns out. For those of us that are fingernail impaired, they are a necessity. However, you can go through a whole handful of them with new retainers (as I did). Seems like they could make them out of something a little tougher. I went through one of them a day for about 3 weeks but now the retainer is looser and I am keeping them longer.

They are nice, but a little to big or long to fit into a person's aligner case with their trays. Also they are rather pricey. I can order other ones through the dental field cheaper. I have to say yours are made stronger and better!

Way to expensive. Other brands work just as good.
