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.

These funnels are great but be careful because they are fragile. If you drop them they will break.

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.

Handmade in a cheap small shop in China, the worst quality I've ever witnessed. The sales pitch is misleading. Each funnel is made of two pieces: a wavy cone shape of semi-clear glass and glass tubing, poorly welded together. Air bubbles are clearly visible in the weldments. I'm returning these, pronto. I wish Amazon wouldn't try to sell us products of the worst craftsmanship first and foremost, no matter how long we spend looking for a particular thing on its pages. I click and click trying to find a quality product and all I get are hundreds of versions of the same crappy Chinese ones sold under various made-up brands. From now on, I will shop around for reputable brands elsewhere on the web, first, then, with a known brand and model number in mind, will check to see if Amazon sells it for a reasonable price.

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

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.
