Thank you for looking♪ This is a BRITA fill & go, convenient for carrying around and equipped with a water purification function. - Brand: BRITA - Model Name: fill & go - Features: Filter device, bottle - Capacity: 0.6 liters Purchased several years ago. The box is slightly torn (see 2nd image). Please refrain from purchasing if you are sensitive about items kept in home storage. It has been stored in a dark place, but the condition of the filter cartridge can only be known after opening, so please only purchase if you understand this.
