150ZL and 150 are black ice. The only difference is that 150ZL has one more LOGO than 150. 150ZL has the ZIPPO logo in the lower right corner, and 150 is a light machine.

By the way, I would also like to remind you that there are the most fakes of black ice on the Internet, especially on Taobao, especially when the price is below 100, and there are also gift boxes with full sets of accessories, all of which are fake, because the purchase price of genuine black ice 150 is around 100, so it is impossible to get/kloc-0.
