@hejowhat yes that's a good idea. I'm just wondering if aluminum heat conductivity might not be ideal for hot drinks ...

@tomdeb @hejowhat we used to use them as coasters where I used to work. They work great.

@kev @hejowhat I might try to convince the kids to make a necklace with #PerfectValentinesDayGift 😂

@stimzim I'm not sure tbh. They'll probably go in a box in the attic. My cyber paranoia just forbids me to throw them away 😀

@tomdeb @stimzim Buy a strong magnet and you can erase everything from the disks (if you want to throw them away).
