Slim mini black leather messenger bag with a long adjustable strap. The leather is from a tannery in Tuscany and has a beautiful suede-like finish on the back side. I get 2 hides in each color - one for the body of the bag (4.5/5 oz) and the other is a heavier weight hide (7.5/8 oz) that I use for the straps.

The back panel hides an interior pocket. Two straps come across the top to attach to solid brass shiny button studs.. The dimensions are ~4.5" x 7". There are 2 small D-rings on either side of the gusset to attach the saddle strap and over-the -shoulder strap.
Messengers come in 3 sizes. This is the smallest that I make and will fit easily into the small matching tote. (This will not fit the new large i-phone). 

All hand-stitched with matching Ritza Tiger thread from Germany well known for it's strength and durability. The bag is roughly 4.5" x 6.5" x 1.5". 

The hardware is all expensive heavy, solid, shiny low-lead solid brass. The bags and straps are unlined, all natural and unburnished.
