These brushes come in very handy for all the little things done in your house. Sealing grout lines is one of the uses.When done,you can just toss the brush or if you are using water soluble solutions you can clean it for reuse. These brushes are also great for cleaning car vents of dust. They can reach down and get them really clean. I also use them for small paint dings on walls. Dab the spot,don't brush.

Was the same price as boar hair. Works perfect for my needs. I use them right now to clean things, when I need a small brush. The horse hair will work great for glue and acid applications.

These brushes are just like what we used when I was in the Navy. These are really good brushes for either small projects or when you have a tight space you are trying to get into. We called these brushes "acid brushes" in the Navy.
