X-Stiff Short Shank Aligner

As the name suggests, these Aligners are extra stiff. Because the material is firmer and stiffer, the Aligner can also be refined in shape. The X-Stiff version is therefore slightly more compact and finer than its regular predecessor. Available for hook sizes 1 to 4 and for hook sizes 4 to 8. Which also fits many hook sizes 10 by the way.
