This product range includes thermal cup and bottle models of different colours and sizes. They all share a gently rounded lid made of a shiny material. Inspired by the round, smooth and natural contours of pebbles, the cover with its ergonomic design is easy to open. The shape of the rim of the cup is fit for human lips to drink ergonomically. The one-touch retractable technique allows easy and convenient one-hand opening while the fastener locks firmly and keeps liquids from leaking.
