This is one satchel, you'll be passing down to your kids! 
I make these bags to be virtually bomb proof from 3.5mm thick full grain veg tan leather. This means that it will take anything that your life can throw at it with grace and style. 
I use one of these satchels on a daily basis myself and I have had no trouble with it for the past 8 years!
I can provide different closure methods if necessary. This particular bag will come with old brass side releases.
The bag itself is around 10 inches tall, 16 inches wide and 3 inches deep.
I can supply with a shoulder strap, a briefcase style handle or backpack straps. Please let me know in your comments when ordering.
If you have any questions, please feel free to contact me.
