*by I***� on 2 April 2025*

Lo uso para cuando voy a correr y me resulta cómodo por su tamaño, de material resistente, a pesar del calor mantiene la temperatura fría sin importar el exterior. Una vez lo olvidé en pleno sol y llegué a pensar que el contenido estaba caliente sin embargo solo se calentó la Tapa por lo que el agua seguía intacta en temperatura. Puedes usarlo y también obsequiarlo a quien gustes, todo un lujo 🤩
