I have ordered lots of glass and other breakables from Home Science Tools, and never has anything arrived in less than perfect condition. They are without a doubt the most careful packers I know.
- Monday, January 05, 2009 Stylish Reviewed By: Jerry I'm homeschooling and all I needed was a beaker but this flask is not only a good item at a good price but it looks more stylish then a beaker. it will make your lab area look like one.
- Wednesday, December 03, 2008 Good Product, Good Customer Service Reviewed By: TANYA I ordered 500mL flasks and when I received them I realized they would probably be too large for what I needed them for. The company was great in letting me ship them back in exchange for smaller flasks and it was all done in a very timely manner which is always a plus.
