Feel free to conov us and request it. :) View the rest of my shop here: http://www.etsy.com/shop/thetwistedscrew **UNDERSTANDING OUR PROCESS** This piece is created by hand using a hammer and metal letter and symbol stamps. Metal stamping is a quirky process - letters and symbols will never be completely straight or centered, darkening may be a bit uneven due to varying stamp depth, and stray marks may occur. These are not defects in your piece; they are what makes it unique and one of a kind. :) ¨¨¨¨°º©©º°¨¨¨¨¨¨°º©©º°¨¨¨¨¨¨°º©©º°¨¨¨¨¨¨°°º©©º°¨¨¨¨¨¨°º©©º°¨¨¨¨¨¨ Please read my shop policies here: https://www.etsy.com/shop/TheTwistedScrew/policy ¨¨¨¨°º©©º°¨¨¨¨¨¨°º©©º°¨¨¨¨¨¨°º©©º°¨¨¨¨¨¨°°º©©º°¨¨¨¨¨¨°º©©º°¨¨¨¨¨¨ New to Etsy?
