Cardstick ruler stickers

These are about some of the most handy things I've ever had. I have one attached to the inside of a small notebook, and the other is on the plastic case of a fresnel lens I keep in my wallet. I've used them dozens of times. There's no issue with durability that I've noticed over 6+ months of being in my wallet. I'll probably buy several more sets in the future.

This is a very smart, very simple idea, and I am happy to have one in my wallet (good for measuring bolts etc.). The metric rule is oddly backwards, in order for it to run from zero up along with the imperial side. The simplest solution would have been to flip the digits over, then when you turn your card over it would still be readable, and also still match up with the other ruler. This doesn't stop you from using the metric side, but it does make it a little awkward. My only other complaint is that it seems very wasteful to ship these in the small Amazon boxes - I ordered two sets, but you could fit 20 into a small envelope...

just okay... I'd hoped for a better appearance but it does what it says it will do.

They stick, but when taking my card in and out of my wallet, going to the ATM, swiping it for purchases, the stickers rip and wear off.Maybe put it on a card you don't use frequently and it would be better?

Waste of time

Good, small gift for people who like to make stuff. Works well on your credit card or license. They're very thin, so I haven't had problems swiping my card at the ATM. Have also been surprised how many people at checkouts ask me where to get them.

Works as described. Relatively easy to install and read. They have held up well inside my wallet. I would buy these again.

Useful but overpriced.
