This is a resin model that faithfully and accurately reproduces the actual bone. It consists of 16 bones in total. This model was cast and polished by hand in 22 steps to make it transparent and visible from all angles. We prioritized smoothing the refraction of light and increasing transparency rather than reproducing details. This allows us to maintain beautiful transparency. Depending on your ideas, you can teach various information, such as drawing fracture lines with a whiteboard pen. It also can be erased. It's also excellent in terms of form. If you want to see details, we have replica model of these bones( LMB-11 and LMB-12). If you purchase LMB-09 and LMB-10 together, you can expect even higher educational effects. This product is all handmade, so the shape may vary from piece to piece.
