Need the perfect finishing touch for your terrarium? Our natural cork lids – also known as cork bungs or stoppers – are just the thing. Available in a wide range of sizes, they’re designed to fit your container like a glove, creating a snug seal for your closed terrarium or glass jar display.

To find your fit, simply measure the internal diameter of your container’s opening and order the matching size. For example, if your jar measures 12cm across the opening, choose the 12cm cork.

These lids are made from high-quality, sustainable cork, and work beautifully for terrariums, DIY storage jars, apothecary displays, and more.

Cork Lid - Perfect Fit for Terrariums and Glass Jars - Various Sizes
From £1.80

Customers praised this cork lid for "fitting perfectly" with terrariums and jars. The sizing guide helps ensure accurate fit, with shoppers saying "it fitted absolutely perfectly." Fast delivery and quality cork material were consistently mentioned. One minor issue: price tags left marks on cork. Highly recommended for DIY terrariums and jar replacements.

I really struggled measuring up for the right size cork bung. My jar is very large and wide and i already wasted money buying the wrong sizes else where. It was a godsend to just put in the measurement of my jar opening and yous do the rest! It fitted absolutely perfectly! Quick delivery too. Thank you so much.

Great service

The team at Sprouts are great! I ordered the wrong size cork stopper for a jar (totally my fault for mis-measuring) and they were so helpful in sorting me out with the correct size.
The cork stopper is nice and thick, seems to be good quality and does the job perfectly after the ceramic jar lid got broken.

Got a really nice sweet jar with a rotten rusty old lid. This was the perfect solution. Wasn't expecting it to be slightly tapered so an added bonus. Really solid bit of cork but still a little flexible. Brilliant.

The cork stopper was perfect for the terrarium I picked up in a charity shop. I spent an age trawling Amazon before finding Sprouts of Bristol on Etsy. Should have gone there first. Great seller. Highly recommended.
