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

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.

Bought 2 opened one later after I came back from my trip for 3 weeks. Picked up second one and didn't even have to open the box I could hear it broken glass inside. The one is fine the other I left here while I was on vacation. Past the time frame to return

I've had these for 6 months and use them with some regularity, and just broke my first one today. I wouldn't say they are unexpectedly brittle or strong, they are just glass. My biggest grievance is they don't fit inside each other so storage is a pain, and in general the tubes are smaller than I'd like, but the dimensions are listed so thats more on me than anything.

Great product. Delivered promptly

These are good quality glass funnels…that arrived wrapped in one layer of newspaper and cellophane wrapping. This product is good but the packaging resulted in damage that can’t be repaired.

Great quality for the price . Easy to clean and store . Using for some hair products and it helps in transferring to other bottles .Packed securely by seller . Arrived in tack . Pleased with purchase .

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