What is it?

It's a decorative charm made with the durable materials and accurate methods of electronic printed circuit boards.

The charm has the mechanical design of a classic dog tag and is 1 mm thick. It has a transparent fiberglass core laminated with copper foil edges, and a coat of saturated red lacquer in the middle. The writing is printed on top of the lacquer with white UV-cured resin ink. On the edges and inside the keychain-compatible hole, a brilliant silver-metallic finish is created by dipping the entire tag in hot lead-free solder, which sticks only to these uncoated copper areas.

This is the exact same process of making functional circuit boards, which gives the charm a couple of unique qualities:

• The details are ultra-precise with sharp and contrast-rich design elements that have feel-able thickness
• The shiny areas have a fine texture to them, from the core's fiberglass weave
• Filigrane-looking and only 2 grams, but very sturdy (impossible to destroy by hand)
• Wear on the edges and keyring-hole exposes the copper underneath the tin coating (this looks cool)
• Heat-resistant up to at least 200°C

Allergy note: Please let me know if you get an allergic reaction from the product (usually a light rash after skin contact). I don't think there's a high enough concentration of Nickel in the lead-free HASL solder alloy that coats the edges and the keychain hole of the tag:

• 99% Sn
• 0.6% Cu
• 0.05% Ni
• 0.006% Ge

Why did you make it?

Circuit boards that have artistic value are usually limited to art on just one production layer (like the silkscreen). With this I tried out using combinations of graphics on many layers to give the design a mesmerizing clarity that qualifies it as a fashion accessory.

And I put different tags behind different keys on my keychain to quickly find em lol.

What makes it special?

It's art or a "fashion" item that's made like circuit boards -- which are usually hidden behind a nicely designed case in order to be fashionable. These tags are meant to be worn and seen prominently!
