I have a portion of the beads (about 80 liters) from the packaging filled directly into a bean bag so that it is slightly thicker. Here, the chemical smell is me already noticed. You can decant After now even a slight chemical smell perceive if you sit right on the closure. But I do not find disturbing. The rest were a little in the fresh air and I have stirred something, the smell has already become considerably less. Best 1-2 days wait until the beads used.
