All the GAN Lubes are silicone based lubricants which is safe to use on plastic. The main aim of lubricant is to reduce friction between plastic contact surfaces which firstly produces a smooth glide and is a more comfortable feel but more importantly protects the plastic from wear.
The GAN 1 Lube is a thin consistency. It is intended to be applied over "base lube" and will reduce abrasion and extend the service life of your cube.
It is packaged in a clear bottle with a tamper-proof cap, and it is available in a 10ml size.
