This is a cute and compact mechanical pencil. The mechanism is flawless and the pencil itself is made of robust stainless steel. It is slightly bigger than the Zebra Mini Mechanical Pencil TS-3, 0.5mm but still very compact and easily fits discreetly in a purse or a shirt pocket. It has even got an eraser hidden below the cap. The transaction was also flawless and smooth. Thanks to the Bumbo team!
