If you're looking for a leather that will acquire a patina and show where it's been, you've come to the right place. The vegetable tanned leathers that we've sourced for the KMM & Co. collection are made without dyes or harsh chemicals. Because they aren't dyed, vegetable tanned leather tote bags and accessories will quickly begin to patina and show wear. Each one becomes a true one-of-a-kind, unique to you and the way you use it.
