Review on Lab-Grade Beaker Shot Glasses, Durable Borosilicate Glass, Set Of 4 by Richard Mangum

These are amazing shot glasses. They have fairly accurate markings from 10 to 50 ml and the top line is about a 1.5 ounce shot. Close enough. These are great little glasses for alcohol shots, or even espresso. They are definitely a great conversation starter and look so much cooler than standard shot glasses.These do not stack so that may be a concern, but other than that, they are probably the coolest little glasses I've ever used. Mine arrived well packaged and were not broken. I know Borosilicate glass is the technical name for Pyrex and is more durable than standard glass so these shouldn't break unless you drop them from high up onto a hard floor. Great product and one of the coolest gift ideas I've seen. Note that these do not come in any fancy packaging, just a plain white box with the glasses wrapped in bubble wrap.
