Failure to do so can have a negative impact on their quality. In case you do need to store Delphibug, please follow the instructions below. Koppert B.V. is not liable for any loss of quality if the product is stored for longer and/or under different conditions than recommended.

  • Useable life: 1-2 days in the dark (keep the bottle horizontal)
  • Storage temperature: 12-14°C
