Mismatched Glassware Unified by Sandblasting
Take mismatched glassware. Sandblast it. Now they are all united with a similar frosted exterior. The Frosine glasses were designed by Michelle Ivankovic, senior designer for Umbra.
Apartment Therapy suggests that they are vintage glassware; the Umbra site says "hand selected". Designers doing such a thing in small quantities is not unheard of, but for a company the size of Umbra to do it is amazing; big companies worry about consistency, packaging, all kinds of things that would make doing something like this more trouble that it is worth to them. Impressive.
