Made using tempered soda lime glass, the product is tough, but may break - this is not covered as a manufacturing defect.
If you have your proof of purchase from an authorised retailer and your glass tumbler has broken within 30 days we will have a replacement glass sent to you and just ask you to cover the cost of postage. If you no longer have your proof of purchase, replacement cups can be purchased here. Make sure you hold onto your plug, band and lid as they will be able to be re used with your replacement glass.
If you are missing a component they can also be purchased separately here.
