"Grid" is designed by Michael Graves. Part of ACME's Collezione Materiali pens, the "Grid" design is made from a hand applied lacquer on a brass barrel with a pierced sheath, plated in matte silver. The pen is presented in a blue wooden ACME box. The box is signed by Mr. Graves in silver marker. This is an extremely limited version of the packaging. Once these are gone, no more will be available for sale.
