Frequently asked questions

How many cups are included?

The listing identifies a 2-pack and lists two straw cups, each with a 5 fluid ounce capacity.

What straw options come with the set?

The component list specifies two straws with valves and two without valves. The listing describes the valve straw as slowing flow and the other as providing steady flow.

Can the cups go in the dishwasher or microwave?

The details list dishwasher-safe and microwave-safe features, but care instructions also say hand wash only. The listing does not resolve that discrepancy, so consult the instructions supplied with the cups.

Are the cups spill-proof?

The title and feature list make spill-resistant, leak-proof and spill-proof claims. The feature description says the dual-seal design helps reduce spills, rather than promising that every spill will be prevented.
