"A Foe-Glass is a type of Dark Detector. It looks like a mirror, but instead of a reflection it shows the enemies of its possessor. The figures appear as "shadows" but become clearer and more visible as the enemies get closer to the possessor."-HP wiki
These earrings are edgy, classy, rad, glam, and major Slytherin vibes. Gold hardware with clear acrylic creating a rad jewel! These are not lightweight, but they are also not extremely heavy. I would rate them a 6/10 on heaviness.
