Quick, received exactly what I ordered plus some free yopo seeds in one week :D The berries look a little over a week old, so they were probably harvested that day or close to it. They immediately sunk in water, so I have no doubt they're viable.
I ordered 2 when it was at a discount price and they were probably getting questionably old to even sell. The two seeds were stuck together by a small amount of mold. I washed them off and the inside seemed to be unaffected.
