Denis Wick Advanced Valve Oil "Last 3 Bottles Bundle Sale"

This is the best valve oil with very limited stock. It is characterized by its silky smooth action and effects that last for 3-4 weeks.
The secret to its smooth action is the inclusion of PTFE in its ingredients.
PTFE is the substance with the lowest coefficient of friction discovered to date.
Furthermore, PTFE also has the effect of preventing vaporization, which leads to long-lasting effects. It can be used not only for trumpet pistons but also for rotary valves.
