This antique calculator brooch is a perfect gift for the little geek inside you, or for the geek friend you love. The chance to learn some Finnish words from the reverse side comes as a bonus.

This is a unique brooch made from Finnish vintage encyclopedia pages. The brooch is well lacquered, so it won't wear out easily. It's weather proof, but extreme humidity may cause damage. My mother tested her paper brooch for machine washability, and based on her experiment I wouldn't recommend it.

1.5"x1.7" / 3,8x4,2cm

See last photo for an example of how I wrap my jewelry. They always arrive ready for gifting or for simply treating yourself to something special.

Frequently asked questions about paperiaarre

I don’t currently make any custom order books, and it’s not really something I expect to change any time in the near future. My Aspergers has the most effect on my time and stress management skills (and sadly I find all sorts of negotiation extremely stressfull, even if it’s with nice people about nice matters), and I’ve simply found it’s best for my health to work at my own pace. This way I can always guarantee the high quality of my work I hold so important. Nothing is designed or finished in a rush, so you can trust you’re always getting the best product possible.
