This rollerball with removable cap has been designed as part of the popular AL-Star collection by LAMY. The pen barrel is made from a beautiful metallic blue aluminium featuring a matching cap that fits over the nib of the pen; the cap can fit on the end of the pen when writing. On the side of the pen cap is a silver toned metal clip perfect for securing into a pen case. There is a carved grey transparent plastic grip for added comfort when writing and preventing you slipping when writing. The LAMY brand name has been engraved into the barrel of the pen for subtle branding purposes. There is a twist mechanism near the cone of the pen which unscrews so you can change the refill. This rollerball pen is under two year warranty.
