100mm Glass Funnel, Short Stem, Borosilicate Glass, Heavy Wall, Karter Scientific 213V12 (Pack of 2)

Nice thick glass used for the funnel making it much more durable and resistant to breaking if dropped. Packaging was also well done.

Nice & thick but a bit small.

Perfect size for filling bottles and flasks.Good price point for two funnels.

The glass is thick and there are no damages on it. Stem is not too long and the neck is not too small. Totally worth it!

I make lip balm and face creams and had been using a small plastic funnel for filling the tubes. I'm happy with these borosilicate funnels. They are thin but strong and resistant to breakage. The small end of the funnel is angled making pouring an easy and less messy chore. I'm very pleased that the 75 mm funnel easily fits into the small lip balm tubes that I use.

Overall I would buy again but they do appear to be a little thin. They were a good price and could be replaced if broken.

THESE ARE REALLY GOOD, THEY WORK JUST LIKE A FUNNEL SHOULD WORK....FIRST RATE PRODUCT. I USE THEM TO MIX STUFF...

was exactly what it said it was, in the answered questions there is an accurate measurement of the stem diameter. the only discrepancy is that the bottom of the stem is angled, which is actually a benefit. some people are saying this thing is flimsy, but I think they were angry because they broke it. this is as solid as you would expect a glass funnel of this thickness, and it has functioned for the past few weeks exactly as I had wanted it to.I use this for pouring my kombucha into grolsch-style bottles and I avoid plastic for health reasons. This funnel is perfect for that, and the price is reasonable considering how difficult it is to find a funnel that isn't a derivative of that stainless steel funnel/strainer combo from china that every company has bought and is trying to resell here.
