We have updated them a bit since that time. They are bigger and will hold better.
We mailed out the smaller magnet to every one of our customers at the time they placed their order. Along with the magnet, we sent a thank you note, some sort of a sales offer and a questionnaire about their experience. The light weight was needed to keep it within the mailing weight guidelines.
The new magnets are handed out by the cleaning crews and at our drop off depots. We also mail some out but there isn't the same amount of literature we are sending.
