Monkey Knuckles - Mini Delrin Edition The new Mini Monkey Knuckles in Delrin are an ultra smooth, and highly portable version of the original. They rival the larger Delrin version in terms of flow and playability, in a much smaller package. They feature a thinner cord (the same used on the wooden versions), which is strong, supple, and abrasion resistant, and since the balls themselves are lightweight, the thin cord is comfortable to manipulate when performing tricks. The knuckles and end grips are machined from high quality POM/ delrin material, which will hold up to any abuse you give them. The larger balls measure XX in diameter, with a 3.5mm bore, and the cylindrical end grips are ~11x11mm with a 3.5mm bore. Each set weighs around XX g all in. They will ship with with two additional strings, a carry bag, an info card, and a couple of stickers. Specs: Includes two "knuckles" ~27mm in diameter, and two cylindrical grips 11x11mm Large "knuckle" bead weight: ~13.7g (yes, they do make serviceable begleri, but a bit awkward due to the size) Small grip bead weight: ~1.2g Full set weight ~34.3g Bore size on all beads is 3.5mm
