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.
