RT Mini Feliks Pillow keychain

The Mini Feliks Pillow is a keyring version of the Meffert Puzzle series, shrunk to a very small size. Its pillow-shaped cube looks almost round, and its soft form lets you see five colours at once. This makes it easier to follow the movement of the sixth, hidden colour on the back, which can help when solving faster.

The puzzle turns very smoothly, just like its larger siblings in the range. As an example of how easy it is to turn, the source points to Feliks Zemdeg's personal record of 7.5 seconds. Reaching similar speeds, however, takes some practice.

Attached to a set of keys, it makes a distinctive accessory for anyone who enjoys puzzles and wants a small, unusual detail to carry with them.
