This large retractable soft brush has a bristle head that measures 35mm wide by 30mm long and is ideal for "first pass" cleaning of larger optical surfaces.

The brush has a retractable action allowing the brush head to be withdrawn in to the handle for safe-keeping. The brush is safe to use on all lenses (including coated and multi-coated).

The retractable brush is large enough to cope with larger binocular and telescope objectives and large enough to tackle SCT correctors!
