Customer Reviews

Black Covers Review by Charlie
Covers are good quality, the silicone that came with them was dried up in the tube, used my own. Had a bunch of unused caps for my iron, wish it came with a few other sizes it didn't include. Overall good value compared to over $200 for the kit from Harley. (Posted on 7/1/2021)
