Small photo album case. It's about 6 x 6 x 1-1/2. It has 48(?) photo sleeves and I place each dubbing zip lock bag into one sleeve. Cheap ($1.00) too! Of course I need 2 of them. Now if you want a dubbing holder for a travel kit, just get a 50 bullet plastic box. Larger caliber, larger compartments. The one I have is a 45. It's the size of a fly box and will hold more dubbing per bullet compartment than you may think.
