Dear JUSTIN HOLLOWAY,

I am really sorry about not having sent the brochure work on time. This delay occurred due to the fact that we had some pending work in arts to be done and therefore could not send you the package.

Next week, Monday, I’d send you all those materials and rather deliver them to you personally. I know this might have an effect on your engagements, but I will try to take care of it the next time

Sincerely,

Marót
