EISCO Curved, Flask Cleaning Brush, 15" - Twisted Stainless Steel Wire Handle - Ideal for Labware, Glassware, Beakers, Bottles, Jars, Cups, Vases up to 6.25" Diameter

So happy that I purchased this brush! It’s perfect for cleaning my flower vases.

This works really well! It did exactly what I needed it to do, help me clean curved vases and flasks. I am VERY happy with the product. The only reason I give it four stars instead of five is because the handle is all wire. This is great because you can use every inch of it to dive into large containers with narrow necks, but it is also a bit difficult to hold on to when you are twisting it around with soap and stuff. We lose length when we buy bottle brushes with plastic handles, I don't want to lose length, but it WOULD be helpful to be able to get more of a grip on this brush.

I was looking for something that was flexible enough to get into a small cruet bottle opening but stiff enough to get the rounded parts clean. Needed that curved part to hold up and this was perfect!

The quality of this brush is very cheap and nothing like the picture and description. The bristles are very soft and would not scrub the items I intended to use it on. Save your dollars

Perfect for cleaning Erlenmeyer flasks

I bought it to try to wash 2l flasks, and it did not work as I wanted. Still a useful tool, it does good work on lab glass.

this brush is better than I was expecting. I am very pleased.

Did not fit in the mouth of my flask. Had to return for a refund
