This is a set of 3 removal blocks, 1 of each style at a discounted price.
 
3D printed blocks designed to fit their respective regulators. Printed with high infill and flexible TPU material to protect your regulators from tool and vise marks but strong enough to help remove regulators. They are not really designed to break Loctite or cross threaded regulators. 
 
** If you need the blocks stiffer, put them in the freezer for 15 minutes**
