20% off the Big Blow blowpipe - normally £57.50 plus vat but reduced for this month to £46 plus vat and free post worldwide. Why not improve your airflow into your pipes? It comes with an inbuilt valve. Please state the size required in the comments section when you check out - sizes range from 7 to 12 inches with 10 inch being the average size.
James will action the 20% reduction at his end when ordered.
