The Fulling Mill dubbing box has 12 separate compartments for holding dubbing selections. It incorporates an original ‘easy pinch’ design that allows quick access with strong magnetic closures. 12-nipples in the lid push dubbing towards the feeder holes. The boxes are stackable and come with a blank card to match the compartments, allowing you to label what you are sorting. Each compartment can hold roughly 1g of dubbing. It’s a must have for all fly tyers. Dubbing sold separately.
