Experience Luxury At Its Finest. After our leather is tanned and prepared over a 12-day period, each Eva tote is made by hand which can take up to another 3 days (a total of 15 days while most leather companies use cheaper leather that take just 1 day to complete the entire process). We go to extreme measures to ensure our customers are getting a truly premium leather bag. The Eva Leather Tote. Made by hand in naturally tanned full grain buffalo leather, the Vintage Eva Leather Zip Tote was made to last a lifetime with a versatile design that makes it perfect for travel, work and everything else in-between.
