Hello!
I have no idea if there's any interest/need for these, but I figured I'd try before just tossing them out.
I have 47 or so assorted cardboard backs from various waves of TMNT toys. A lot of the originals are in there (4 turtles, Casey, Shredder, April, etc.) as well as some figures from later in the line.
No blisters/figures are included and all will have some level of damage from where the blister was removed.
If you want them, just pay shipping + paypal fees and they're yours. From what I've seen, shipping will be anywhere from $10 to $14 depending on where you live. Feel free to check for yourself. My zipcode is 18017 and the box will weigh about 4 lbs, 6oz.
If you're local to Bethlehem, PA, you can pick them up for free.
