F-ONE brings wood back to life. It is a complex blend of natural tree oils and seeds. After treatment the fingerboard leaves it clean and treated for a long service life. It does not contain any Lemon Oil, which could also dry waxes or distillates from oil, silicone or water. F-ONE leaves the fingerboard as new, great playable and very pleasant to touch. It never sticks. The used mixture is immediately soaked in the wood and gives the fingerboard a new look for a long time. Suitable for all types of fingerboard, from rosewood, maple to ebony.
