Rene Martinez Graphit All Guitar Lube Set

Looks fine at first. Expensive for what it is, but should last a lifetime, works wonders - what's the catch you may ask? The catch is that the bottle will not and can not stay in one piece, the weak spot is the bottom end that's heat/pressure sealed (poor design), I guess they expect you to buy it again after their poorly made bottle breaks. Now my expensive guitar case is full of hard to clean graphite lube, and I'm out of 19 euros. Otherwise a wonderful product that really helps the tuning stability, but I will not buy from this manufacturer again, and if you value your money I suggest look for products that come in at least decently made bottles.
