As part of the novel design of the Flexi-Hex® Bottle Kits, these Flexi-Hex caps are used alongside the wrap and sleeve to secure your bottles with a diameter between 105-110mm in place. This ensures that movement is minimised during transit and helps reduce the chance of breakage that would normally occur. 100% plastic-free and made from over 85% recycled content, we’ve appointed Flexi-Hex products a 5/5 on our eco-score, meaning these caps are recyclable, sustainable and carbon neutral. So as well as being great for protecting your bottles, the Flexi-Hex caps are great for protecting our ecosystem too.
