Dear Xie san,
Thank you for your prompt reply.
You have to inform the exactly information what happen and how propose for the solution to BW ASAP.
For the low viscosity bulk, BW may be ask you about the compatibility test because Naris already suggested this bulk was suitable for the bottle with pump as per the attached file. Naris should be find out the reasonable answer for BW.
For the next time onward, we suggest you to check the overall information is accurate before send to BW because we don’t want to waste the time like this.
