Handmade products are more often than not imperfect, asymmetrical in shape or finish. The beauty of handmade objects lies in its imperfections. One must understand that human hands can never replicate the exact same thing twice.
Artworks and other products are made entirely by hand and from scratch, you will often find irregularities that are never seen in mass produced objects. These irregularities are its intrinsic character and not a flaw.
