Our take on the 48 Custom 12 oz oslo - Graystone - Microwave Safe

The Oslo is a 12 oz ceramic mug with a matte colored exterior and a glossy white interior. It is microwave safe when the imprint is non-metallic, and hand washing is recommended. That makes it a sturdy everyday mug for home or office use, and a common pick for branded gifts and corporate orders. Against plain promotional mugs it stands out on the two-tone matte finish; against dishwasher-safe stoneware mugs it gives up convenience.
