Oils and waxes is something you should prefer to keep in a jar especially manufactured for this purpose. We have a number of silicone and plastic jars with non-stick coating for easy and smooth storage of your concentrates. In case of emergency you can use parchment paper but an airtight jar is always the best. There are a number of models with different features and sizes so make sure to take a look through all of them to find the one that suits you the most!
