Cardstick turns any card into a ruler
We're not sure how often you REALLY need a ruler when you're out and about, but these Cardsticks still seem like a very clever idea. Attach the stickers to any card and turn it into a ruler you can take anywhere with you.
Available from TheCardstick for $3.99 (for three different colours).
