DNM-37 is a water-based piece lube from Cubicle Labs, built to give a puzzle an immediate burst of speed. Piece lube means it goes on the plastic contact surfaces inside the puzzle, not on the springs or core. The formula absorbs and holds moisture from the air, which slows how quickly it dries out.

Why you'll like it

• Two drops is the whole job — add, turn to break in, done.
• Thin and water-based. It adds speed rather than weight.
• Works on every puzzle shape, not just 3x3. Megaminx, Square-1 and big cubes included.
• Three sizes: 3cc to try it on one puzzle, 15cc if you maintain a collection.

Performance and design highlights

• Hygroscopic formula — it pulls water molecules out of the surrounding air, which slows drying.
• Speed-first on the feel scale, with lasting as its second trait.
• Handles the pieces only. Your springs and core still need a silicone lube.
• Safe to touch.

How to apply it

• Add two drops inside the puzzle.
• Turn for a minute or two to break in and spread the lube evenly.
• Reapply when the turning starts to feel dry.
• Keep it off the metal. Screws, springs and washers need a silicone lube — DNM-37 contains water, and water on metal hardware causes corrosion over time.
• Do not ingest. Keep away from open flame and high heat.
