This multi-purpose brush is handy because it is not only shrink but also provides a plug is to better protect and transport it. The hairs are secure (check all the same time) we lose avoiding and / or more annoying, some remain (for example) "glued" to the lens of a lens.
The total length of brush (with cap) is 8cm or approximately the same size as a lipstick tube.
I recommend this product if you also fill it with a blower like this:; = 1 psc
