PB PRODUCTS - X-Stiff Short Shank Aligner

As the name suggests, these aligners are extra stiff. Because the material is stronger and stiffer, the aligner can also be slightly refined in shape. The X-Stiff version is therefore a bit more compact and finer than its regular predecessor. Available for hook sizes 1 to 4 and for hook sizes 4 to 8. Also fits many hook sizes 10.
