Current price $239.55
Metal Types: Platinum

These 10.1 mm diameter "monster" plain friction ear nuts are sold by the piece — order 2 for a pair. Made in the USA to the highest standards, these oversized backs use substantially more material than lightweight economy ear nuts, delivering superior stability and security for holding larger or heavier earrings firmly in place. Their generous size also makes them far easier for customers to handle and significantly harder to misplace.

Monster-size ear nuts are especially popular with customers who demand the safest possible friction-post backs. The 10.1 mm measurement is taken at the widest part of the nut. Available in four precious metal types to match your earring post material.
