Thank you for viewing. 14k Nib width unknown Stylo Art Karuizawa Tulipwood, known as "the wood diamond" in Europe. This is a rare model, of which only 5 were sold in 2010, with the aim of Bungubox participating in the "Certified NPO J.POSH Japan Breast Cancer Pink Ribbon Movement" by donating a portion of the sales (Kingdom Note has a sales history of stainless steel nibs).
