This Copper (Cu) disc measures 24.26 mm in diameter and 1.75 mm in thickness, weighing approximately 7.55g. It is precision machined from 99.9% pure copper, featuring ground surfaces and laser-etched labels, making it an ideal choice for collectors and scientific experiments.

NICE SAMPLES
Perfect size and thickness for my purposes. Really nice finish The etched Cu symbol looks good for display purposes, but I did not need that feature. Would be nice if blank discs were available.

A little small but nicely made.
It's ok, good to have as a hand sanitizer but I would actually prefer something larger for this purpose. It's just a glorified penny really that cost $10. No big complaints but I wish it was bigger.

difficult to handle
Thought these would work like the Copper Touch device. Hopefully it will.

Get a .999 pure Copper Bullion Round instead
The idea is neat but it's far too expensive. Also the comment about it being a "penny", well not unless you are talking about a wheat penny, and several of them. Modern pennies are mostly zinc.
