The cost is $42 (since there is a $2 paypal fee) plus $15 in shipping. They are 28x18x18. Pelvis inlet is 11cm They are made of PVC. They are not fully jointed, but will move a little. In order to give everyone enough time to order, I will put the order for them on Jan. 20th. I will let you know when they arrive and are ready to ship.
