"I'm taking the tests out of the bulky boxes and putting ones of the same make in a single ziploc bag with the instructions."
@KentChristine - FWIW, I emailed Abbott/Binax to ask if there was a reason to keep the OTC tests in the box. I emphasized this was not the proctored tests but the self-test kits.
"Thank you for contacting Abbott Technical Services. Unfortunately, the test kit components can not be removed from the packaging until you are ready to start testing. Doing so could result in damage to the components or an invalid test result. Please keep the test kit box intact until you are ready to begin testing."
Not sure why and I did not follow up to ask for specifics.
You should do what is comfortable for you but thought I'd let you know what they said.
