Clip top preserving bottle. 500 mls. Food grade bottle. These bottles are designed for preserving all drinks/cordials etc but especially those with fizz, the thick glass and clip top are designed to take the pressure…….think cider and elder flower champagne. Please note…..if you are interested in buying a few please message me for a separate postage quote……it will be cheaper in bulk than the algorithm of my website shows. Thank you.
