vintage? Plastic back XXL Baby Diapers Adult Small <31"

Up for auction is a brand new, unopened pack of diapers.  I can't find a manufactured date anywhere on the package, but they are the 'old' style based on the two tapes on each side, the plastic backing, and the size of them.  They are an adult size SMALL but could also be used by older children.  They are sized by waist/hip size & will fit hips and waists from 20" to 31" - which some people would consider a Medium.  They have a PLASTIC backing in a peach color.  In the picture, I put one of the diapers in with the picture of the pack.

From the package:  "superabsorbent polymer - provides maximum protection; keeps moisture away from the skin.  Multi-strand elastics - for a close fit and leakage protection.  Blue Acquisition Layer - helps to keep skin drier.  Wetness Indicator - signals when brief should be changed"  Two tabs on each side for a better fit; 12 in the package which actually says briefs but to me that would imply that they are the pull up kind which they are not. 

I will ship discreetly and within a day of payment usually.  Please feel free to email me with any questions you may have.  Thanks, and happy day!
