Description Blues Bros Eliquid Concentrate – Is a powerful blackberry & blueberry eJuice, with added hints of soul and blues. Fruity, strong and soulful, berry lovers are sure to enjoy this smooth flavour. PLEASE NOTE: This is a flavour concentrate. This is not an eliquid. This concentrate is used to mix your own eliquid using PG, VG and Nicotine and should not be vaped on it’s own. This is a highly concentrated flavour additive. Vjuice Eliquid Blues Bros Concentrate is a PG based flavouring which is sold in 30ml bottles. For best results we recommend using between 10%-20% flavouring in your eliquid mixture, depending if you like a strong flavour or a subtle one. Generally if using less than 10% there will not be much flavour at all, and if you use over 20% flavours can be too strong or harsh. Our eliquid concentrate flavours should be ready to vape 10 minutes after it’s mixed, but feel free to steep it a while if you wish to blend the ingredients better, but this is not required.
