^^^ I guess I'm not sure what you mean by 'the big kit'?
The last 8-10 years I have been given a kit that arrived in a box the size of a wristwatch box.

All have come back negative.

I remember when they first came out...they just sent a cardboard with a swab stick. Just swab some on the cardboard and send it in. One year, I forgot about the holiday and it sat in the mailbox for two days in the middle of the summer....lol

Now they use a tube filled with liquid. The cap has the swab and is returned with the test in the tube.
