Humbrol Enamel Tins
These are the traditional modelling paints, oil based, that used to be sold in model and toy shops up and down the country. The paints each come in a small tin, and brushes can be cleaned using white spirit or turps.
Revell Enamels are the same thing, to the point of being near identical. Due to lesser popularity, we are phasing out the Revell tins and so have put the remainder in this category and reduced them to clear. They're all brand new tins though.
