The Hultafors Dry-Marker has a grip-friendly and ergonomic design. Supplied in a holster with a built-in sharpener for clear markings. It's easy to remove from the holster, so you don't have to let go of what you're working with. The shape of the holster ensures that the pen stays in place even when you move. The pen can be used whilst in the holster or removed completely depending on your preference. There is a hole in the bottom of the holster, this allows dirt and moisture to fall away from the pen, providing a longer life. The lead is easy to change and refills are available.
