Aligner Retainer Kit - Remover tool + Retainer Case With Vent Holes + Chewies Aligner Tray Seaters (Blue)

The "ventholes" are a joke...it's "behind the hinge" per their description...the size of a piece of dust. It's basically the hinge itself. It's also too ill-placed to do the job.

The tool is so helpful removing my Invisalign braces.
