This is such a nifty tool when it comes to sanding nubs from hard to hold pieces or applying decal stickers. This vise has been a great purchase if you need something to hold if you have shaky hands.
These are definitely the best synthetic brushes i have ever used.
Especially for free-hands I always reach for these, I have found the paint leaves the bristles so much better than even natural hair brushes.
I also prefer these brushes being slightly stiffer than natural hair ones.
The only downside is that they are synthetic and after moderate use they will develop a bent or curved tip.
