The cork band is a natural, biodegradable product made from the waste product of wine cork manufacture. It is designed to fit into the undercut on our glass cups to provide thermal insulation, and holding comfort while drinking. The cork may stain overtime with use, we encourage you to view this as a natural patina to the product.
Due to production method and cork being a natural material, there can be slight variances colour, height and width of the band. As a result band fitment will vary, some can be moved slightly on the cup, and some may fit tight, with no movement. Both are fit for purpose as intended, to protect your hand from heat when holding.
For longevity, we advise hand washing only and to not remove the cork band. Repeat dish-washing will cause the band to become discoloured and stretched.
Please treat your cork bands with care, especially when fitting it to your glass. Over time, the cork band will form a tight bond with the glass cup, if you need to remove your band, make sure you follow our instructions to avoid breakage.
