Low Adhesive Labels or Dual Use Peel Off Labels

Can anyone suggest a website name that sells sheets (3" x 3") of the newer low adhesive labels. These are labels that you apply to another paper product, that allows that have a low adhesive property and allow the consumer to peel off and save and use (i.e. coupon) in the future.

An additional question would be a source for those peel off labels (2" x 3") that adhere to a permanent adhesive backing label, but the secondary label is a transparent material that will allow them to be applied to a product. The primary label is a printed label that can be peeled off and retained by the consumer. The primary label typically peels off cleanly, with no adhesive residue and leave the paper product it's stuck to legible because the secondary label that remains is of course transparent.

Any help on either of these. I've tried some searches, but the problem is I'm not sure the trade name for either of these types of labels and as usual, I actually receive too many results to wade through from a search request.
