I have not bought from the shop RetroBagsClub, but I have it saved in my favourites because I really love looking at their animal bags. Normally bags like this are not at all practical but it does seem like you can comfortably use the interior like you can any other bag.
On Etsy I normally look at the reviews, and photographs from the reviews. All these look fantastic!
This shop also makes painted, tooled and regular bags. The prices are not too high either. I would love to hear from any of my readers who have one.
