The Platinum Pro-Use has two innovative features called the "snork system." First, there is a spring mechanism that helps cushion impact when writing, thereby reducing lead breakage. This feature can be kept on, or turned off. Second, the lead pipe/sleeve is adjustable, from 0 to 4.5mm long. This allows you to customize to the exact pipe length you like, depending on your specific needs. For example, you might want to adjust your pipe to the thickness of your ruler, or you might want to store the pipe for travel so that it doesn't get bent. Your choice of .3mm or .5mm in Matte Black with Violet, Wine Red, or Navy.
