This rubber stamp was created by Lamp x Paperi Brocante, who produces original stationery in Kyoto, Japan.
The stamp was created with a scientific image, as if a researcher scribbled down a formula in his notebook.
The scribble style is very cool!
It will make even a simple paper look stylish at once.

Size: 3 cm square (seal surface)
