I have a Vaja Classic Black Leather Case for sale. The case is brand new and never used. It's the Vaja 667 - CLASSIC -- Flip Top leather case for 3G Apple iPod 30 GB with snap closure AND Screen Protector!
Pictures are HERE --> Pictures of the Case (http://f2.pg.photos.yahoo.com/ph/bman492002/lst?&.dir=/Ipod+Case&.src=ph&.view=t)

Not sure if it will fit the 10 and 15 GB models. It's all black leather with the snap closure for the front. I just got it in the mail a couple days ago, when I already had my other case.

The website for these cases is: www.vajacases.com

They are made and shipped from Argentina and the total price from Vaja for these cases is 55.00 with the huge shipping charge. So this is a good deal because you dont have to pay the shipping charge from Vaja. Feel free to e-mail me: BMR@FUSE.NET if ya have any questions...This case is awesome and made with only the best leather. Looking for $45 shipped! The shipping will be through USPS Priority so you'll have it in 2 days...
