Hi Arianna,
I confirmed again today, and I’m sorry, I made a mistake before.
The UV coating I mentioned, which changes color under UV light, cannot protect the formula from UV interference. It is not the protective coating you are looking for.
May I know if the coating to protect the formula is a must-have? We have not met this requirement before, so if it is required, we will need some more time to check.
Also, just wanted to check if you received the courier fee invoice I sent earlier. If yes, could you please help arrange payment when convenient?
Thank you.
Best regards,
