This is a real unique robot mug. Nothing mass produced from ETSY.
From the seller:
A unique, hand-crafted mug of cone-6 stoneware (dishwasher-safe), that recalls sci-fi toys of the early Atomic Age. A very solid, charming, and delightful piece! Glaze is ASTM-certified as food-safe. Measures 5.6 inches high and and weighs 14.2 ounces (403 g) with a capacity of 10.5 fluid ounces. As with all non-industrial ceramics, use in a microwave oven is not recommended.
