Glass Funnel Set, 4 Pcs Lab Borosilicate Glass Funnels, 100mm (170mm Length), 75mm (130mm), 50mm (90mm) & 40mm (70mm) Diameter

I love these as that they are glass, but they break really easily.

Nice. Exactly as expected.

One funnel was shattered upon delivery. Nice set. Ordered another and was fine. Glass is somewhat thin.

very nice, fast delivery

I use these in my houseplants. Watering is made easy - just plant the funnel and fill it when you water. No water dripping down the leaves to mop up, no overwatering and they're nearly invisible. Those glass bubble things are pretty, but they need to be pulled, filled and replaced. Once the funnel is placed, it never needs to be moved - until your beautiful, thriving plant needs a larger home.

I mean they're funnels what can you say they work until they break and they break if you just barely tap them so you know buy them if you want but just be super careful with them I mean I know you're probably thinking yeah they're going to break if you're not careful but no good laboratory funnels don't break by just a mere tap they break easy like strong glassware but these are so fragile I can't emphasize it enough

Delivery arrived intact and quickly. No complaints

These funnels are atrocious. The bodies of the funnels are made of very thin glass and the necks are shoddy with roughly cut ends. To top it all off, one arrived with a crack in the neck and another with the neck completely shattered. Pro tip: a box of glass funnels should not make a jingling sound when shaken. Don't waste your time with these. Spend a little more and get good ones.

Packed very well and arrived in perfect condition

Robust ottimi

Don’t know if made from borosilicate glass, but they handle shocking well. Very well made.

El cristal es muy frágil, uno me llegó roto.
