Lubicle Black is a thick but low friction metal-based lubricant by Cubicle Labs. Designed especially for metal-to-metal and metal-to-plastic contact, Lubicle Black is ideal for lubing the core and hardware of your puzzles. Apply a small drop to the head of each screw and the bottom of each center piece to unlock the best smoothness and speed a core lube can offer!

Caution: High risk of staining, keep away from garments. We recommend lubing your cubes on top of a paper towel or other disposal surface. To remove the lube from your skin or other surfaces, wash thoroughly, rub with silicone oil, and then rinse with soap and water.
