This is a SUKALA hydrogen water bottle that came with the first-time purchase set of LAVA and Rintosull. I haven't had a chance to use it, and it has been stored at home, new and unused. It's a lightweight type, perfect for hydration during yoga or Pilates, and the design is simple. It's also recommended for those who are just starting hot yoga or fitness. 【Condition】 New, Unused
