What is difference between Ver 1 and Ver 2?
Based on the feedback from users, MAGBULL did a lot of improvements on the new Version 2 Black Python Tight Bore Series
- being made with a new machine and new coating process.
- using different packing (10pcs packing) to prevent "bending" during the shipment.
