The brush that don’t drop / Brush

Nowdays,we are often encounter many problems when we use brush.Such as paint or oil paint along the brush flow to the hands.or when we want to change another brush by half-way and have no proper place to put lead to pollution of grounds.
so we make the rubber boot that can be combined with brush.it can cling to the brush.And when you use brush,it have another function to block paint or oil paint run off.and don't contact ground
when you put.At same time,in terms of design,it have reasonable size and won't effect brush when you use.
We hope when the human use brush ,we are both care ourselves and environment.
