This cylindrical kubur or pen case is made of three component parts and veneered with mother-of-pearl scales. The detachable lid is crowned with a green emerald finial which rests on an amber wood knop surmounted by a silver rim around its edges. When opened, the inside of the case reveals a tubular papier-mâché body covered in red leather. In addition, beneath the case there is also a detachable base concealing a silver inkwell with a lid in the form of a rococo shell.

There is a similar Ottoman pen case with mother-of-pearl scale decorations in the Nasser D. Khalili Collection (accession no. MXD116).[1] Furthermore, there is another comparable pen case, bearing the tughra of the Ottoman Sultan Osman III (r. 1754–57), held at the Museum of Turkish and Islamic Arts in İstanbul (Accession Number: 4040).[2]
