Hi Judy, I got the bags yesterday, they look nice! Thank you for your nice support and we will make bulk order next week... Very Very nice label!

—— Saowa from Thailand

Hi Judy, yes, these bags worked well and can be reused. Our research work is over now, we thought that the gas only stored for 5 to 6 days in these bags but we stored the gas more than 20 days still the gas composition was same...... Very good! (Feedback about the New Devex bags.)
