This is a stainless steel mug from Early Times, a promotional item from about 20 years ago. I haven't used them, but they've been in storage for a long time. I'm selling them for the cost of shipping, as I hate to throw them away. I hope someone will use them. There are 6 white mugs and 4 brown mugs. Height: 8cm Diameter: 6.5cm Diameter with handle: 8.5cm Shipping with the original boxes will cost ¥870 for shipping and Mercari fees, so the price will be ¥1000. If I remove the individual boxes and ship them within 60cm, the price will be ¥900. Please message me if you'd like the cheaper option. Thank you for looking.
