Most of the other pens you see on etsy are made from standard pen kits. But by creating a pen without a kit, you get something truly unique and custom. And since each pen is made by hand, no two pens will every be the same making this a truly one-of-a-kind pen. This particular pen is offered at a slight discount to most kitless pens due to the threads on the cap and body only being single start threads. This means that it takes more turns than your typical pen to remove or secure the cap.This pen will come with a standard black ink cartridge, and an ink pump for using bottled inks. This pen will come in the black linen box pictured. This item is made of acrylic.
