Several listings explicitly state hypoallergenic or nickel-free construction. One listing specifically mentions hypoallergenic premium brass with thick plating.
Offerings include single-pair options and multi-pair sets; common counts shown include 3-pair and 9-pair packs.
Post-style backings described include disc-style (flat) backs, butterfly (friction) backs, and other post-closure hardware designed to keep the earring in place.
