⭐︎Brand New⭐︎ This is a pick used to remove Invisalign (mouthpieces) for orthodontic treatment. It allows for smooth removal by hooking onto the aligner. I was told it was a good idea to have one, and I bought it from my orthodontist for just under 2000 yen, but I finished my treatment without ever using it. If anyone is interested, please consider purchasing. Invisalign / Kirei Line / Retainer Retriever / Easy Lift Material: Stainless steel Thank you for looking.
