Please be sure to read the profile (..) This is a balloon bag with many tucks. It's a bag that can hold a long wallet, smartphone, etc. Perfect for a quick outing... It's sturdy because it has a bottom board. Bottom board size (12cm long, 21cm wide) Size: Width 21.5cm, Height 16cm (43cm including handle). Please allow for some margin of error. I also have larger sizes available, so I would be happy if you would take a look. Please understand that this is handmade, so there may be loose threads or slight imperfections. Thank you for looking.
