Thank you so much for all your help this time.

Thank you so much for all your help this time.
I have safely received the test results and confirmed the contents.
Thank you as well for sending the sealed envelope under such careful, secure handling.

Also, I enclosed a toothbrush on Thursday, September 14th, but since it is no longer needed for re-testing,
could you please dispose of it for us?
Sorry for the trouble, and thank you very much for your assistance.

We are truly grateful for your courteous support from beginning to end throughout this process.
Please forgive us for expressing our thanks over email, but we wanted to convey our appreciation once again.

Thank you very much for using our testing service this time.
We are all delighted if this testing was able to be of even the smallest help to you.

We wish you continued health and happiness going forward.

We also confirm that we have received your request regarding the disposal of the spare "toothbrush" sample.
Thank you very much.
