If you do a search, you will find some Gustto threads & posts.
I love the brand, I have 6 bags (I think), 3 Bacas & 3 Parinas. They are all soft and great. For a long time, their quality control seemed to be non-existent, as you will find if you read what we had to say about them on tPf. Some made in Mexico, some made in China. I sold a Parina on ebay only to have it returned because the buyer didn't believe it was authentic based on the tag. I took pix showing her my Gustto bags had differeing tags, linings, etc. I love those bags, the Parinas can carry a ton (I use one really beat up looking one the most at flea markets) and the Bacas are just Bacas, unique! One of the Bacas I have is the big size and it seems to have the same pebbled leather that is used on the Coco Duffels.
Glad you are enjoying yours too. You won't see yourself coming and going carrying a Gustto.
