I don't know how the customs in the UK works but prepare yourself you might pay UK sales tax + custom fees on the total amount. I prefer an alcohol lamp instead of the butan torch. Shellac is melting under 100 degrees Celsius (around 85 degrees if I remember right. Buton torches can leave marks and damage the laquer, pearls.... . Just a reflection, but I'm very oldfashioned when it comes to saxes and dito repair!!!
