Designed for the laboratory but can easily be used in your home.
Premium polypropylene plastic allows for them to be (virtually) indestructible. (Real talk, you definitely can break them if you smash them with a hammer or stomped on them or something. You just won't break them by dropping them on your kitchen floor or bumping into something - normal day to day use.)
Ships in frustration free, simple cardboard packaging.
Premium glass beaker mugs also available, search for PHBKM500
