Thank you for viewing! This is the MIDORI Ruler Aluminum Wood 15cm Brown x Brown 42280006. I purchased it new, but I'm selling it because I bought another product and haven't had a chance to use it. It has a luxurious feel with natural American walnut wood and an aluminum body. It gives a great sense of ownership and seems like it would increase motivation for work. Great for collectors too! #Midori #Ruler #NaturalWood #Luxury #Aluminum #15cm
