I bought the yellow one!! I fell in love with the unusual sketchbook-like shape at first sight. I usually use a small bag, so I bought it without worrying about the capacity, but when viewed from the side, it looks like a triangle, with a narrow opening and a gusset that widens towards the bottom, so if you put things near the opening, it won't close all the way... It doesn't hold as much as I thought it would, considering the gusset. But the design is overwhelmingly superior, so I love it!! Cute
I bought this in light blue. I love the cute sketchbook-like design and the foil-stamped letters. The soft colors make it easy to match with a variety of outfits. After seeing the photo, I was worried whether my wallet would fit, but the bottom is wide so a 3cm thick tri-fold wallet fit in without any trouble. However, the top is narrow so be careful not to put too much inside as the buttons will not close. It was big enough to fit A6 size paper. It didn't fit an F1 sketchbook like a bag, but an F0 did!
I bought the light yellow one. It looks like a real sketchbook and is very cute, so I'm glad I bought it♪ The inside is small, so I personally think it's best to carry the main backpack with the letter-style pockets and put things you want to take out quickly in the pochette. It's an accent for your outfit, so I think it's fine to carry both the backpack and the bag!
