Due to the unfortunate fire at the AKM manufacturing facility in Japan, we have a very limited supply of this item. We urge anyone interested in this item to buy it while supplies last. Despite our very best efforts to get these products to customers as soon as possible, the impact of the fire on AKM’s operations may cause shipping delays. The AKM supply volatility will not improve until the end of April 2021.
