Product Description

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!

After some time sitting unused, this lube may separate. Simply stir it to thoroughly remix the solution. Then use as directed.

Lubicle Black comes with a green dispensing tip, a lube tip cap, rubber work gloves, and an introduction card.

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.

Our Promise to You

All of our products are guaranteed to be free of defects, or we will replace and reship at no cost to you. Please contact us within 4 weeks (28 days) past the delivery date to report any issues with items you have purchased.

Please note that some new cubes when being used for the first few times may experience what is termed a "pop". This is when one or more parts of a puzzle pop out without any damage actually being done to any of the pieces. This also occurs from time to time during normal usage. Pops are typically not considered a defect if the parts which come off can be reassembled by hand.

The corners on 2x2 puzzles should not be twisted as doing so may snap the piece. Damage caused by corner twisting is not considered to be a defect.

very black and made my cubes black

Decent Core Lube

Great core lube, that reduces spring noise. It is a bit hard to clean up and slows the cube down a little.

It is so good, it is the first core lube, but it made my cube soo much faster

Lubicle Black is amazing

First off this is my first core lube so I can't compare it that well but some people say it is better than other core Lubes. Personally I agree 100%. I put some in my MoYu RS3 M 2020 and it completely got rid of the spring noise (which was pretty bad before) except for one side but I can only hear it if I turn really slow right next to my ear. I also put it in my new main which is the DaYan GuHong v4 M and it immediately made the turning of the sides a little faster and smoother. What I really like about it is after about 150 to 200 solves out of no where the cube got incredibly smooth and with the magnets in the cube it controlled perfectly. My only complaint with it is that it is quite messy so I recommend having a towel and wiping your hands continuously if you get it on you so you don't get it on the pieces because it isn't very easy to get off. Also, this could just be my fault for putting too much in the core but it gets on the tracks of the piece a little bit but it is easy to get off of the tracks and I don't notice it affecting the cube or spreading to the outside. This could be my fault like I said because I might have gone a little heavy on the amount of it I put in the core. Lastly, this could be taken as a good or bad thing but I can almost guarantee that the plastic in your cube will wear out before this does because even after putting a piece under running water the stuff wouldn't come off. I see that as a bonus though because of how much I love the cube.

So, basically you should definitely buy it but be careful when applying it so you don't get it on the pieces.

Stainy core lube

My cube didn’t feel different at all

My Dayan tengyun v2 does not feel different with this but my other 3x3 feel faster and smoother with this, but I am disappointed, thank you.


This lube isnt really anything new to me, its way to runny and gets everywhere which makes it hard to apply, and after that i didnt notice any difference than with other lubes, this is not worth it, just get any other heavy lube

joe k.
good but

the lube is good on 3x3 and sometimes 3x3 and any other cube that has a core but i cant find how to do it on a square 1
