DESIGNER: Felix Ure MATERIAL: Brass SIZE: 1.5" x 1.3" (3.8 cm x 3.3 cm) While not a puzzle, Felix Ure's Spartan Top certainly has puzzling qualities! Created to optimize spinning times, Spartan is precision machined from solid brass and fitted with a tungsten carbide tip. In his [video][https://www.youtube.com/watch?v=QaKnfRxfKY4], Felix demonstrates a single spin lasting over 17 minutes! Spartan is an exceptional exception to our typical puzzle offerings and one I hope you enjoy as much as we have. Spartan measures 38mm in diameter, 33mm in height, and weighs 76g. The brass is unfinished to patinate over time slowly. Handling Metal Puzzles All metals tarnish over time. Residual oil and salt from handling speed up the process and may leave undesirable fingerprints. Occasional use of our Metal Puzzle Polishing Kit with a coat of Renaissance Wax will keep your metal puzzles in tip-top shape!
