Review on ☕ Ultimate Insulated Ounce Double Wall Coffee Brown: Deliciously Fresh Coffee in a Stylish Cup! by Brian Cruz

Nice size. Suitable for microwave and dishwasher. However, I only washed the outside of the mug with a damp cloth, no soap, but the writing came off. Not happy about that! So I would never put them in the dishwasher. This is not a leakproof device, although the description says 'unlock, lock'. The spout closes but does NOT always lock in the closed position. I will leave them anyway, but you must be aware of these issues.
