This is a small holder to hold a comb vertically. No guarantees your come will fit this design, but mine fits perfectly. The opening is 86mm long, 8mm wide.

I needed a way to organize everything on my bathroom counter a little better. This is a nice compact design to get the comb to stand upright and stay out of the way. The holes allow airflow so the comb can dry out if needed.
