Why are bands scaled?

The wemo was originally inspired by seen a nurse who was consistently taking notes directly on the surface of her hand. We wanted to give that nurse, and others like her, an alternative way of jotting down notes, without affecting the skin.


The band is designed with a scale on it, because of focusing on the measuring tape that nurses always carry.


Challenge by a industrial film manufacturer in Tokyo

COSMOTEC is a manufacturer of functional films such as adhesive tapes and protective films for various electronic devices. Our technology and products have been applied to TV, tablet computers and many other digital appliances we usually use.


Special coating for smooth writing

We focused on the quality of writing and erasing so that the product can be used on 
the front line without any worries. We have developed a coating that does not leave erasable marks while maintaining writing comfort by applying the technology used in our core business of industrial-use films and adhesive sheets.
