Letter to an aunt thanking for a birthday present

Dear Aunt,

I am writing this letter to express my heartfelt thanks for your wonderful gift of a beautiful wrist-watch on my birthday. It is really the latest in design, looks very elegant and beautiful and is, of course, quite costly too.

I promise to make good use of it and observe punctuality in my routine.

With regards to dear uncle and lots of love to Anita and Abhishek.

Yours lovingly,
