In general this is not a bad product for the money. My disappointment is that this is a scaled down model. I bought two 3B Scientific skulls 18 years ago which were clearly cast from the same mold as this RONTEN skull. (Precise asymmetry of skull and suture lines.) The 3B skulls are small enough to be considered "life size," yet they are approximately 3/4 inch larger than this model. I give medical seminars and travel a lot so my skull can take some strain. They need to be replaced. I was hoping that this skull would fit the standard brain models and intracranial membranes I already have. Not this case. But overall the stitching and holes are present and anatomically correct, unlike some others I've seen at Revain for a comparable price. As an anatomy teacher, I would recommend it as a teaching tool. And the shipping was SUPER fast. Received this within 48 hours of ordering and am not a Prime member.
