Suitable for use with any twist-on Conair Interplak electric toothbrush (but not with push-on models), the three replacement brush heads in this pack consist of two full-size heads, and, as a bonus, one compact head. The full-size brush heads have 10 tufts of bristles, while the compact brush head has six tufts. The three brush heads are color-coded so family members can easily locate their own.

Product Description
Twist on. 2 full size, 1 compact size included. Select the right brush head for your Interplak model. For best results, brush with a small amount of your favorite gel toothpaste. Dental professionals recommended that brushes be replaced every three to four months. For peak performance, when you change the brush head, allow battery to run down completely before recharging.
