Plakira Unbreakable Glass 400ml Set of 6 Price: ¥787 (per piece) • The Plakira Crush Tumbler series is a Japanese-made glass that won't break even if dropped 1000 times. Compared to ceramic or glass tumblers, it has low thermal conductivity and good heat retention. It is dishwasher-safe, microwave-safe, and alcohol-sterilizable, making it easy to clean. • Large 400ml size. There is a cloudy area on the sticker part at the bottom of the glass. I think it is in good condition without scratches, but please understand that it is a used item.
