Thank you for viewing! This is a set of 4 cold-sensitive tumblers that change color below 5°C. Capacity: 380ml They are very light and have a smart design, making them easy to use. You can enjoy your Super Dry even colder than in a glass! I will ship them in a box. It will be a bit cramped in a 60-size box, so please understand. Originally, they were attached to a Super Dry case with double-sided tape, so there may be some tape residue. There are no issues with the contents. Please refrain from purchasing if you are overly concerned about this. ✖️ No price reduction due to shipping costs. Thank you for your understanding.
