Imperial maple burl pen blanks. Solid big leaf maple burl with amazing figure. These are oversized, unsurfaced pen blanks/turning squares, measuring just over 1″ x 1″ x 5 1/2″, are not stabilized with acrylic resin. With the industry standard pen blank size being 3/4″ x 3/4″ x 5″, and the occasional “jumbo” 7/8″ x 7/8″ x 5.5″ being the alternative, we have chosen to offer our Imperial maple pen blanks as an even larger blank in the highest quality. Apt to accommodate many creative concepts, these beauties are so versatile. Known now as “Imperial”, we believe these blanks to be named accordingly. Acer macrophyllum, out of all the maples, is widely considered to have the most pronounced and beautiful figure in its burl. We’ve hand selected these incredibly figured pen blanks/small turning squares to signify the quality that “Imperial” represents. As an alternative to other maple varieties, such as Acer saccharum or Acer saccharinum, we are excited to make ours available as a superior option. The Imperial oversized blank is excellent for multiple applications. PLEASE NOTE: blank size may very 1/16″ (+/-) square and 1/4″ (+/-) in length.
