The pyrex was just as described but instead 500mL instead of 300mL. Not sure why 300mL is in the pic, but these are 500mL. Perfect for anything, but i got them for E-Liquid for my vape.

I like to make my own facial astringents, hair rinses, floor and window cleaners, and so much more that I am finding I can make simply, greenly, organically, and inexpensively at home. I’m growing increasing amounts of medicinal herbs and flowers in my small garden and love fresh teas from my own plants. These Pyrex flasks are great for brewing tea as well as keeping it in the fridge, creating concoctions for the home and storing them, mixing cocktails, drinking almost anything out of ... They’re easy to grab and “stir” the contents by swirling. They never tip over. They’re beautiful. I’m never going back to regular glassware or stemware - these are so much more practical and useful.

We are really happy with our erlenmeyer flasks. Back in high school, 20 years ago, I was really into chemistry. Eventually I moved on to Berkeley to get a degree in chem. My high school sweetheart would always give me roses, and for one special occasion he put roses in a flask for me. At that time you had to buy flasks at special chem stores, which was costly and time consuming. Fast-forward to present day, my then high school sweetheart is now my fiance (with a break of 15 years). We want to decorate the tables with roses in erlenmeyer flasks for the wedding. They had to be Pyrex glass too. With weddings being so costly, and having to cut out some things we wanted, we were happy we to find a set of erlenmeyers for a great cost to use as decorations. These will make great vases. The delivery was quick. We ordered days before Christmas and we don't have Prime, so package took about a week. They were carefully packed with bubble wrapped, seperators, and boxed within boxes. Thank you!

Beautiful glass work! They were a huge hit at my son's end of the year mad scientist sleepover. Had a couple fall off a table and hit the pool deck without breaking.

It's Corning. Actual Pyrex. Tough, well made and will last. Perfect for the lab but also super handy when working with all sorts of materials around the house.
