Our 1-of-1 headphones include our Stabilized + Resin and Rarity units. These unique headphones are available 3 times a year during our Spring, Hot Cup Summer, and ZMFnovember drop events, each individually photographed and usually split between 2 drop days per event. Many are ready to ship at time of release, but due to the high volume/short timeframe nature of the drops, you can expect these one-of-a-kind headphones will ship within 1 to 8 weeks.
