UM2+ Calibration card is NOT waterproof plastic!

I had some tiny amount of PLA stuck to mine and decided to soak it in warm water. Big mistake. The card delaminated and is screwed. It is not solid plastic throughout.

UM - May be an idea to let your customers know this. Keep it away from water!

Well is just a paper card with a fancy logo, paper doesn't love water

If you want something more precise and durable, buy a Gauge feeler. They are very cheap, and a nice tool to have overall.

Felt like plastic. I'm a slow learner.

You are one of those people who need a warning on a microwave oven that it should not be used to dry pets, aren't you? ;-)

Indeed it should be something with a calibrated height and durable. But also, well Gauge feelers are really cheap a dn easy to find. You will get more precision with it.

Some users just get a visit card. I think the width of the card is 0.15? Or was 0.10?

Now have some gauge feelers - thank you.

ahoeben: I only microwave pets on low. But they are delicious!
