Alchimia presents here the medium lid for the Vacumax machine, that allows you to close your jars (up to 20cm) with a firm and airtight sealing when connected to a vacuum machine .
It is made of thick transparent plastic, and has a rubber band to ensure a good sealing between both parts.
It also has a valve to connect the lid to a vacuum machine, so oxygen won't oxidize its contents, while the smell will remain inside the jar.
