I would have just used some sticky tape, but what do I know.

I thought sticky tape had the risk of creating high voltage static - not the best for electronics. Related: https://en.wikipedia.org/wiki/Triboluminescence

Edit: I couldn't find a good video but skip to 4 minutes in this is perhaps relevant: https://www.youtube.com/watch?v=LQBjRF9mX1Y Cheesy cheesy video but kinda sciency.

Someone once related a story from working in a 3M factory that made tape dispensers from bulk tape in the factory. The rolling machines to unroll the tape from the bulk rolls generated so much static electricity that walking through the aisle underneath would make your hair stand on end.

It was a bit stronger than just affecting hair-

Isn't that solved using kapton tape?

Why not put in a plastic ziploc bag? Lots of stuff from Amazon comes in plastic bags. I got a pack of 2x3" recently, that size would be perfect for this.

I bet it is enough not to move around in the envelope. I guess there are anti-static bags if paranoid.

I googled and saw gummy glue is used to stick credit cards to paper. That led me to think it's a great choice for this.

its sometimes called booger glue or snot glue. Apple uses cut flaps to hold their sim tools without the need for chemical glue. same concept will work fine here. I buy all my sd cards directly from a manufacturers site, only from the manufacturer, such as samsung or westerndigital dot com, avoiding any affiliate or 3rd party vendors that can sneak onto sites like which do on the apple store. 0 fake cards this way

What about residue?

There are thousands of sticky tapes, some designed to have no residue.

Here is one I’ve found for example [0], although a double sided one might “look more professional”.

Cool find, thanks! If gummy glue fails or is hard to source then I will definitely try this.

When i ship out collector / trading cards, common practice is to tape the card in between 2 slabs of cardboard to prevent bending (this ofcourse being inside of a sleeve / top loader plastic liner). Usually the protective case is taped to the cardboard with blue painter tape. It doesnt leave residue behind on the cardboard nor the plastic holder

I have bought ink-on-calfskin art and had it shipped to me, the artist wrapped it in parchment paper and taped the parchment envelope to the inside of a cardboard sandwich.

But for SD cards, I would expect affixing it to the inside of a cardboard sandwich with masking / painter's tape to be perfectly adequate, though not by any means pretty.

Painters tape.

Good idea, the microSD cards could be easily be affixed to the invoice / instructions sheet with a square of blue painters tape.

I wouldn't fault a manufacturer / vendor for doing this. Sure, it's not "wow", but exceedingly practical which is commendable.
