I use these small brushes occasionally around the shop for different projects. I had been buying them at the $1 store in a 5 pack and decided I wanted to get a little more for my money.I will say these aren't nearly as good a quality as the $1 store brand, the bristles pull out a lot easier and don't seem as good of quality. I always make sure to pull on the bristles a little bit before using them, so I can get any loose ones out.Despite the slightly lower quality, I would buy again because you get a lot for the price.All these acid brushes have death wish -- none of them are crimped fully.Doing it yourself never works right (you nee to have a good die to do that) -- so they are crummy to use.This one doesn't shed as much as other!Got these for my wood gluing projects. Works great to get even coat on wood surface. Inexpensive enough to throw away when done.These work well for flux, some paints and cleaning. But don't wash between use - they'll rust almost immediately. So for a single use - or using all day with flux, for example, they work great. Using a second day is probably a bad idea as they start to rust.Good value for once or twice use with contact cement. Also fine for solder flux. I will keep a bunch around all the timeI go through these brushes quickly, so I like the quantity and price. I also appreciate the stiffness of boar hair, which allows more control than softer bristles. The problem is shedding. I don’t have a problem with occasional shedding. That happens. With these it’s consistent and it’s something I have to constantly watch. Adding another crimp seems to help, but that’s an extra step I’d rather not have to do.Good for disposable glue brushes but if the material is thick or slightly tacky, the bristles can pull out and get stuck in the glue. Better for thinner applications than thick.The brushes lose bristles easily when using them for paste. They may work fine for a substance that is not as thick or sticky. Not the greatest for flux/acid as advertised.Can’t beat the price. Great quality. Will buy againGood value here, just what I was expecting.seem to be decent quality, i like them
