Nylon Test Tube Brush, Bottle Cleaning Brush, 0.3-0.5" Tubes, 12 Pack

I was having a tough time finding brushes the right size to fit into my 1/2" diameter hummingbird test tube type feeders. Either they were way too big or way too small. Toothbrushes wouldn't fit either. I wish I could have found them in smaller quantity that a pack of 12, but I'm just happy to have found them. The bristles continue right over the end, unlike some others, so it's easy to clean right up to the end of the tube. They clean well. No mold in my hummingbird feeders!

like that the ends can get into corners

Works great for cleaning out test tube

Medium quality. Bristles are really soft so it wont do much scrubbing.

I liked these. They hold up well.

I like the brushes but the hole in the handle won't fit over a peg board hook. I guess I'll just get a larger ring and do it that way. All my other tube brushes have a larger hole.
