Kilner Square Clip Top Bottles

While the clip-top mechanism provides a strong seal, these bottles are primarily designed for non-carbonated liquids like juices, oils, and cordials. We do not recommend using them for secondary fermentation or highly carbonated beverages, as the pressure buildup can compromise the glass or the seal.

Yes, the glass body is dishwasher safe. However, we recommend removing the rubber seal and metal clip mechanism before washing to ensure they remain in good condition and to prevent any potential rust on the metal parts.

Yes, Kilner offers replacement rubber seals. Over time, the rubber can lose its elasticity or become stained, so swapping them out is a simple way to maintain an airtight seal and extend the life of your bottles.

The square design is primarily about space efficiency. Unlike round bottles, square ones sit flush against each other, allowing you to pack them tightly into your fridge or pantry shelves without wasting space on the gaps that naturally occur between round objects.

While the clip-top creates a very secure, airtight seal, these bottles are intended for upright storage. We advise keeping them vertical to prevent any slow seepage, especially with thinner liquids.
