Thank you for viewing. This is the RazoRock HOLLOW HD LONG (100mm) Handle. The material is SUS316L, and the knurling is deeply etched, making it very non-slip. It can be used with almost all razor brands except Fatip. This is a hollow HD type long handle (with a cavity inside). In the fourth photo, it is compared with other handles. The top one is the item for sale. Please note that this is the handle only, and the head is not included. Thank you. #DoubleEdgeRazor #RazoRock #RazoRock
