Early on, Goodnature discovered that not all gas canisters are made equal. They tested dozens from different makers around the world before choosing the highest possible quality made of recyclable steel and a dab of silicone to keep your trap running smoothly. To maximise the life of your trap, it is highly recommend you use the Goodnature-branded canisters. Each canister contains 16g of CO₂
30 x 16g of CO₂ Canisters.
