THAT IS FRIGGING AWESOME. I didn't think it was possible reading your post, but then I tried it myself on a test wallet and was able to reveal the inner flap without disturbing the tape. That's a superb low-tech work-around, nice job.

I could add a third sticker requirement to cover the open fold - could even be a nice circular hologram of a BTC or something. Or, I could change the design so it includes an extra cut in the middle like so:



This way the tape holds down the innermost flap as well.

I can't quite decide whether it's better to have more stickers plastered on the thing, or require that users make an additional (farily deft) set of cuts. Opinions?


Good idea. I'll have to experiment with dry heat (if Niko hasn't already) to see if these tamper-evident stickers are susceptible.

Thanks for the excellent feedback. Just sent you a beers-worth of BTC to your address.
