You can create items (tokens) without listing them for sale, or you can create items on your stores by using the listing page.
This will let you mint your token without listing it for sale. It will be created on the blockchain and in your wallet. You can then transfer it to anyone, or list it for sale at a later point.
You will need to fill out the basic information about the token and then you will have one transaction to submit. That transaction will create your new token on your smart contract and then it will be in the wallet that submitted the transaction.
