Torquetum Illustration Keychain
The torquetum or turquet is a mediaeval astronomical instrument designed to take and convert measurements made in three sets of coordinates: Horizon, equatorial, and ecliptic. It is said to be a combination of Ptolemy's astrolabon and the plane astrolabe. In a sense, the torquetum is an analogue computer.

Perfect for a memorial keepsake to have with you at all times. The quality of the image was perfect and I couldn't be happier.

Acrylic Key Ring, Rectangle (double-sided)
Zazzle Reviewer Program
The acrylic keychains are well made and those that I have been using for some time are just as perfect as when they first arrived. Absolutely no issues or problems. Love how the printing turns out on these, whether image or text. I always go for the two-sided to double the creativity and fun. Nice to have an image on one side and text on the reverse.
