Gunprimer-Staubbürstenstift

It fulfills its purpose very well. I use it mostly for dust cleaning after sanding.

I used to either blow or rub my freshly cut/finished parts, getting dust everywhere.
Now the dust brush takes care of removing debris and dust.

You could probably get a similar brush in the makeup section of the super market. But finding such a high density brush with stiff bristles in this quality will probably cost you the same as going with this product.
