The Posits were created for promotional market use. The goal of these posits are that they are to be given to Doctors and other health companies At Your Door Labs works with to promote their testing services. Here on the post-it is the company logo, website, and phone number. On the PostIt, it is established that the client can come to At Your Door Labs for all your testing needs. These PostIts are to be used between doctors and their staff, as well as anyone else who will happen to need something to write on.
