She`s a flower • In love with Jorge Guerrero Jr Est. 2012
Bought these for my bf but I'm curious whether both laces are suppose to glow or not when light reflects on them. They are 3/27 Chuck Posite "Purple Haze". Bought them for 250 for his birthday on 4/20. Please help, I've researched and found nothing. Thanks
