Hedwig Bollhagen’s Canada mugs, model number “526,” are extremely popular due to their relatively large capacity of 0.2 liters. A distinctive feature is the mug’s straight, cylindrical shape, which makes them resemble a mug with a handle more than a traditional cup. With a diameter of seven centimeters, these eight-centimeter-tall vessels are almost as tall as they are wide. Thanks to their compact wall thickness, these mugs offer excellent insulation. This keeps tea, coffee, or cocoa hot for longer. Incidentally, these 250-gram coffee mugs originated from a commission from Canada. But Hedwig Bollhagen liked them so much that she promptly added them to her production line.
