Expertly handcrafted and signed by Harold Bieber. Great new design using an ultra smooth and quiet ball bearing turning system! Add to that the absolutely perfect images from perfect mirror assembly and you have a great one of a kind kaleidoscope!Check out the feedbacks from people who have bought a Bieber scope - a recent one, for example: "stunningly beautiful kaleidoscope!" Another one: "Beautiful wood and mirror work, great images!" This is a beautiful scope but the best characteri...stic of a Bieber scope is the quality of the images. Check out the photos. This is a superbly crafted kaleidoscope made from one solid piece of ambrosia maple! Ambrosia maple is a highly sought after wood because of the unusual patterns made by the ambrosia beetle. The wood is not damaged in any way but the designs in the wood are always unique. In this piece you can even see some tiny holes made by the beetle. Being made from a solid piece means there are no glue joints to come loose or become unsightly. The beautiful grain of the ambrosia maple is enhanced by a hand rubbed smooth finish and fantastic images are created by a perfect 30-60-90 mirror arrangement. These mirrors give beautiful images but you rarely see them because they are so difficult to assemble. This scope is 100% hand crafted using the absolute best quality of materials. First surface mirrors, hand formed glass shapes, dichroic glass, focusing lens in eyepiece, smooth 360 degree pivot turning, and bright interesting bangles in the object end all combine to make a one-of-a-kind scope that is truly a work of art. The oil object cell causes the bangles to fall slowly and quietly into place! Look carefully at the photos and notice the smooth finish and the beautiful wood grain of the ambrosia maple. About nine inches long and 2 1/2 inches wide, the scope comes with a matching ambrosia maple stand. This scope was turned on a lathe into the shape shown, and the object end turns "like butter" completely 360 degrees, but the best characteristic is the quality of the images! Some typical photos were taken of the images in this kaleidoscope to give an idea of colors and patterns but they don't do justice to the brilliance and clarity of the real image in person! Look carefully at the enlargements of the photos to notice the great images only achieved by perfect mirror assembly! Because you may think buying a quality kaleidoscope on line is chancy (although, in this case it isn't), your satisfaction is completely guaranteed. For any reason whatsoever, if you are not satisfied, I'll pay for return postage and gladly refund your money.
