Materials, sealing, handles, straws and packaging define the version.

Define Use and Capacity

Agree capacity, dimensions and colours around the channel and use. Existing projects include 30 oz and 40 oz; the final configuration follows the approved sample.

Identify Materials by Component

Identify the inner wall, outer wall, lid, straw and seals separately. Different components may use different materials, so one material label cannot describe the entire tumbler.

Review Assembly and Presentation

Review sealing, handle fixing, coating, base marking and the retail box. Product information should correspond to the actual materials and version.
