This is to inform you that your letter of April 4 has been circulated to me, as I am in charge of such requests. After your inquiry, I looked into the matter of supplying your firm with suffocation warning bags. Yes, we do carry these bags in various sizes. They alert customers to potential child hazards. Due to the fact that these bags are required by many government agencies, we keep them constantly in stock. They are compliant with FDA and USDA regulations. On each bag is a message that is printed in English, Spanish, and French. You will find that items slip easily into these poly bags that are open-ended. According to my records, they are available for immediate shipment.

Your Task. 

Revise the following wordy openings for messages so that they are more direct and concise. Write an appropriate subject line and opening sentence for each one.
