Review on StanceMagic Set Of 20Pcs Black 12X1.25 Extended Tuner Lug Nuts - Open End, Cone Conical Taper Acorn Seat (60 Degree), 2.4 Inch Length, 19Mm 3/4" Hex - Compatible With Nissan Infiniti Subaru And More by James Mcphearson

The paint wears off a little bit each time you touch them with a wrench. Also, the threaded hole isn't concentric with the cone or barrel of the lug nut, which causes the lug nut to not completely contact the lug seat on the wheel. This can damage the lug seats on the wheel and cause the lug nuts to come loose over time. Pretty unsafe if you ask me.
