Design story & product details

Nobody else is in this glass shop, and that is the whole joke. A giant steel robot arm is in the middle of a pour, swinging a molten orange ribbon toward a hot bulb on a rod, while gritty cream stencil letters on this long sleeve tee warn: please don’t startle the robot.

My favorite detail is the row of little glowing bulbs on rods by the furnace, as if the robot has been practicing. Give it to the friend who just took a glassblowing class.
