Hi:Still cleaning cupboards. We found three boxes of 3M Tattle-tape DAC-1 for cassette tapes. I have no idea of how many strips are left in each box. A couple of them have the blank labels in the box that you use to cover the strips. One box does not have any labels. Does anyone out there still have cassette tapes in their collection? If so, do you use 3M security strips on them? These boxes have been in our cupboard for an unknown period of time, but I would guess, around 15 years. If you would like to have them, I would be very happy to send them to you. Please include your Rides code.

If we do happen to have it, would you like us to include it with the tapes?
