These mitten blockers were designed by the Hubby and printed here at home by either him or our youngest son. The 3D print filament used is PLA, which is made from cornstarch. Its a very strong, durable material and is also biodegradable (under specific heat circumstances, you can't biodegrade it at home).
Mitten blockers measure 10.5"/26.5cm long by 3.75"/9.5cm wide.
The price is for one pair.
