  • A very fine calculator

    my smallest calculator to date!

    It's cool and works for calculations, up to 10^8 - 1, which is sufficient for most cases.


    Misses points on usability and ease-of-use since I don't know how to make it calculate roots. Misses some features compared to electronic calculators or paper and pen.

    I used it as a decoration on my bag and the chain broke after a a while. Will probably get a new one next time I order though :)


    Somehow not mentioned here, but it "Brings you joy and enhances your IQ all the way" :)


    Never runs out of batteries, and it holds keys. I love this product. i bought one for me, and one for my mother who didn't know how to use an abacus.
