The coffee canister is high borosilicate glass, rated −20°C to 100°C, with a silicone sealing ring and a press-button lid. The storage jars are clear glass with a solid wooden screw lid and a silicone gasket.

Every jar is 9.5cm across, so only the height changes: 250ml is 7.3cm tall, 350ml is 10.3cm, 650ml is 15.3cm, 950ml is 20.3cm, 1250ml is 25.3cm and 1550ml is 30.3cm. The coffee canister is a separate 1.7L size, 24.8cm tall and 11.2cm across, holding roughly 600g of whole beans.

Coffee gives off carbon dioxide for several days after roasting. Open the valve for the first three to five days so the gas escapes, then close it for a full airtight seal.

The glass bodies and silicone rings are fine to wash normally. Hand-wash the wooden lids and dry them straight away, or the wood will dry out and split.
