Thank you for viewing! This item is a fixed-tip mechanical pencil 0.5mm made by Mishin Craft using black persimmon wood, based on their MDS1 model. Black persimmon is said to appear in only 1 out of 10,000 trees, making it a very rare and valuable material. This is a handmade item, so please refrain from purchasing if you are looking for perfection. The thickest part is approximately 11.3mm. Weight: 25g The item used to prop up the pen is not included. The wood cube will be included. I am listing this at a low price, so please refrain from negotiating a discount. Please be sure to read the profile before purchasing.
