Shorts / Pants button replacement using M3 x 8 mm screw, Designed this for some old shorts that i cant seem to get rid of... after the ones i bought online for it where worthless. The online replacements always fell apart then you would have this tiny sharp screw wondering around your house somewhere, or even worse pop off in the middle of the store and you're wondering around with crap in your hands and holding up your pants. YIKES!
