Cork breathes, glass does not
A cork stopper allows a slow exchange of air and moisture, which keeps a planted terrarium from going stagnant. That is the reason most terrarium makers choose cork over a glass or plastic lid.
Corks for terrariums
Wide cork stoppers and lids for glass terrariums, carboys and display globes, in sizes up to 210mm. Cork breathes, which is why it suits a planted terrarium better than a sealed lid.

A wide cork with too little length will not hold its own weight in the neck. For anything above about 100mm, choose the longer option where there is a choice.
Carboys and demijohns vary widely, and antique glass rarely matches a standard size. We make bespoke corks to order — send us the measurement and we will quote.
Prices exclude VAT, volume discounts apply automatically at checkout, and there is no minimum order.
