Adjustable Beard Comb 9–13 mm

The Prewave adjustable comb trims facial hair between 9 mm and 13 mm. It attaches to compatible shavers for wet or dry grooming. The black plastic guard suits daily beard maintenance.

Replacement Guard For Listed Shavers

This comb replaces a lost or damaged original guard on models BT1217, BT1218, BT3221, MG3721, MG3722, MG3730, MG3731, MG7730/15, MG3721/14, MG7770, MG7785 and BT3233. The upgrade is worth it when the old comb no longer locks securely or its teeth are bent.

Fixed Length Range And Wet Use Only

The comb offers a single adjustable span from 9 mm to 13 mm and cannot reach shorter stubble or longer beard lengths. It is designed for water exposure during shower trimming and simple rinsing, not for vacuum collection or powered length displays.
