Yes, you read it right. Hario makes Labware. And Labware crossed with Hario provides you with the coolest way to decant or serve your coffee. This 300ml conical beaker is made to the highest standards and looks amazing - as well as achieving an excellence in chemical durability and heatproof quality (apparently). Another useful little feature are the 50ml markings, all the way up to 300ml. This makes it perfect for mixing exact cold brew ratios with milk or water! Oh, and if the feeling takes you, you can also test it in a laboratory setting.
