A folding ruler with superpowers

Our durable and precisely engineered ruler and hinge mechanism is infused with a patented substance called Biomaster which contains a silver biocide that protects the product surface by pro-actively inhibiting the growth of micro organisms like bacteria.


It is also reassuring to know that the antimicrobial properties of our folding ruler do not wear off. This is because the Biomaster silver biocide is combined with the base material before it is moulded into shape, so bio resistance continues for the lifetime of the product.


Biomaster is a totally safe substance that is also used in medical, food and water applications.


Superior user experience

Constructed from a durable thermoplastic polymer, our ruler is designed to withstand the rigours of school life. It has a sturdy feel in the hand and a folding mechanism that snaps into position when opened.


In addition to the fully opened setting, the hinge mechanism also has 3 additional angle snap points - 45, 90 and 135 degrees - so it can also be used to draw angles as well as for traditional ruler work. 


Proudly made in Britain

We are immensely proud to be able to state that our rulers are designed and manufactured in the UK which makes our delivery footprint into UK schools an eco friendly and light one.


A ruler that cares for our planet

All the materials used in the construction of our ruler are made from recycled material wherever possible and made with the utmost care and consideration for the environment.


Our ethos is to design and make things well so they perform and last. But do that with the utmost regard for natural resources and carbon consumption. We also use zero plastic in our packaging.
