Miya Pottery ◎ Water Bottles: 3 x 2L Size Guide: (115 x 110 x 285mm, capacity approx. 2L) ◎ Portable Bottle: 1 Size Guide: (Φ65 x 170mm, capacity approx. 400cc) Fill the bottles with tap water and let them sit for 6 hours or overnight. The water will become mellow and delicious. If you want to drink it cold, remove one shelf from the refrigerator or place it in the vegetable compartment. This is a drinking water storage container. If you only use it for water, there will be no slipping or water stains, so no cleaning or boiling is required. These water bottles were purchased at a department store. After being used a few times, they were stored in a dark place. Upon inspection for listing, a chip was found on one of the 2L bottles (photo 4). There is no problem with the function, but please be aware of this.
