List of products by manufacturer Strefa Kostek

Strefa Kostek is our own brand. We have been running a puzzle cube shop since 2013, and under this name we sell the products we needed ourselves when working with cubes: lubes, a cleaning agent, small accessories and extras with the shop logo. These are not cubes. They are things that come in handy for anyone who solves, lubes and looks after their cubes. That is why this category has a few specific items rather than a wide catalog.

Adheron cube lubes from Strefa Kostek

The brand's best-known product is the Adheron lube series. Each bottle holds 20 ml, and the lube comes in three versions with different viscosity:

• Adheron Lite is the thinnest version in the series. It suits a cube that should turn lighter and smoother.


• Adheron is a medium-viscosity lube that works well for regular lubing of the layers.


• Adheron Heavy is a high-viscosity lube. It slows the cube down and gives you more controllable turning. It also works well for lubing the core and springs.

You can mix the versions. Cubers often combine Heavy with Lite to set the cube's smoothness somewhere between the two. Thick lube noticeably slows a cube down, so with fast models it is best to start with a small amount and add more gradually. Adheron lubes are also sold through international distribution, so they are not available exclusively in our shop.

Cube cleaning and care accessories

• Isopropanol (IPA) in a spray bottle dissolves old lube, glue and dirt without damaging the plastic. It is useful before re-lubing a cube and for cleaning its outside.


• The felt squeegee comes in two sizes: small and large. The felt edge helps you press down and smooth stickers or film without scratching the surface.

Logo extras and gift voucher

This category also includes small items with the Strefa Kostek logo:

• Cube logo is a set of 5 stickers with the shop logo, available in versions matching different cube sizes.


• SK Cube Cover is a cube cover with the shop logo.

There is also a gift voucher. It is a good choice when you are buying a gift for a cuber and do not know which cube or lube to pick. The recipient can choose the products from the shop themselves.
