• A low-alkali method.
• It was born as a freeze-drying manufacturing agent and is also ***ful for the highest-grade, highly-airtight storage.
• Equipped with the characteristics of a vial bottle and the ease of a screw port bottle, it has a cap for heat and freeze resistance.
• Beca*** the entire cap is a screw cap, safety is also excellent.
