Helix Oxford 30cm folding ruler. Because it folds in half, this ingenious ruler fits into most pencil cases and means you don't have to compromise with a shorter, perhaps less useful ruler.
The innovative snap fit folding hinge was first patented in 1990. There's nothing complicated about it: no locks to be unlocked or catches to be caught. You simply… fold it in half!
Made from clear plastic and marked in black with centimetres and millimetres. Unlike the Helix Oxford wooden ruler, this one isn't much good for knuckle-rapping.
Orders placed before 3pm Monday to Friday will normally be sent out the same day.
FREE Royal Mail Standard delivery for orders over £40, and just £2.50 for smaller orders. Royal Mail Priority is available as an option, for £3.50 on orders over £40, £5.50 on smaller orders. Express available for £9, or FREE with any order over £400. No delivery surcharges for Northern Ireland, Highlands & Islands or anywhere else!
International deliveries vary in cost, so you'll need to add the items you want to your basket, and enter the checkout to see the options for delivery. Prices and payment methods will reflect your country, and many countries have all taxes and duties included to make things easier and more predictable.
For all orders outside the UK, heavy orders may cost more to send, but the shipping cost will be displayed in the checkout before you commit.
