Meet one of my tiniest butterfly art journal ever- totally handmade, with leather-like cover and mixed media papers inside. The journal is closing with elastic and few charms attached to it. He is the biggest and oldest of the two tiny blue tweens, but only by few min and few tiny centimeters.
7,5x 9,5cm (2,95"x 3,74"), 20 pages (40 in total).
As it is a butterfly book, you can take out the pages at any moment, work with them on flat surface, arrange them to your liking and of course- add more pages if you'd like.
The Butterfly handmade tiny art journal is the yin, to your yang. You've found what you're looking for.
