Pro Grade Acid Brushes 3/8" – Disposable Glue Brushes 72 Pack – Soldering Flux Brush for Woodworking Glue, Epoxy Resin, Crafts, Paint, Grease & Industrial Applications

good price and quality

Good enough for the money, quality is definitely adequate. While not the highest quality, the quantity for the price makes up for it. I use these for applying flux to pipes as well as using with solvents such as alcohol to clean residue from (electronics) soldering and they hold up reasonably well. Occasionally they lose some bristles, but it's not a huge deal given the price.

Goo buy for mundane activities

These are your helpful one-use disposable brushes. Size is right for my needs, I use for quick little paint jobs, applying resins and sometimes lubricants. Bristles shed easily, so keep that in mind. But a good value for the price.

I use these for spreading glue on my wood projects and they (as with any acid brush) will drop a bristle from time to time on thicker applications. I also use this to apply Bionide to the roots of my crape myrtle tree to get rid of the sprouts. Highly recommend

Lifetime supply of glue pot brushes for under 20$, can’t beat it!

I mostly use these as glue brushes for woodworking. But whether you’re using them for flux or glue, the idea is the same. Use one to apply and spread whatever it is you’re using, then toss the brush when you’re done with it. I suppose you could clean and reuse them — and maybe I’ll start doing that — but they’re cheap enough that you don’t have to.

I use these to spread wood glue. They work but are constantly losing bristles while spreading the glue. May work well for welding and soldering, but not so well for woodworking.
