Frequently asked questions

Is the KALU Cup really leak-proof?

Yes, when it is sealed properly. Before you head out: close the button lid fully, check the silicone ring sits flush all the way around, and check both lid pieces are screwed on tight. If the drink is hot, leave the lid open a few seconds before sealing to let the steam escape. Tip it upside down for a few seconds: no drips means it is sealed.

How do I clean my cup?

Hand wash with warm water and mild dish soap, then air dry with the lid off and both lid pieces separated. Wash the silicone ring separately once a week, along with the groove it sits in, and dry everything completely before reassembling. See the Care Guide for more.

Can I use the dishwasher, microwave or freezer?

Hand washing is recommended. The cup can go in the dishwasher, but high heat and strong detergents can affect the exterior finish over time. Do not microwave it (the body is stainless steel) and do not freeze it (the insulation is not designed for freezer temperatures).

What is the cup made of?

18/8 stainless steel, copper lined, with a ceramic interior. BPA free and lead free. Tested to EU food contact standards. Capacity is 350ml.

How long does shipping take, and how much is it?

Orders are dispatched within 1-2 business days (excluding weekends and public holidays). Standard shipping is NZ$9.90, NZ$12.90 or NZ$15.90 depending on order weight, and the exact amount is shown at checkout. Delivery time depends on your location and the carrier. Read the full Shipping policy.
