DOUBLE-WALL GLASS MUG410 WS01

It's light and the rim is smooth, and even with a large glass of hot drink, the glass doesn't get hot. What's more, it's dishwasher-safe, and I really like that. I'd like to replace all of my mugs with these, but the fact that they can't be used in the microwave is a problem. When I look at other companies' products, there are many that can be used in the microwave, so I think it's probably also a matter of price, but I'd like you to consider making a product that can be used in the microwave. If it's this shape, I'll definitely replace all of my mugs.
