As part of the Flexi-Hex Bottle Kits, when used with the Flexi-Hex Bottle Sleeve, these protective caps help to secure your bottles that measure between 75-84mm in diameter. The kit includes a wrap and a protective sleeve, which once constructed, forms a protective packaging design that cushions your bottles to reduce movement and minimise damage that can occur during transportation. The Flexi-Hex caps are part of an eco-friendly premium bottle packaging that are plastic-free, recyclable and carbon neutral. Made from over 85% recycled materials and completely biodegradable, introducing Flexi-Hex into your ecommerce operation is a great way to help the environment.
