Although we explained the product properly before purchase and stated in the product description that it was shrink-free, after receiving the product, they asked us to return it because we didn't need it. The rest of the time, the prompting was great. I wish they would look at their shipping schedule. I received a prompt the next day after purchase.
When I tried to pack the shrink-wrapped product in a pack-only package, they started to say things like, "We don't know if the pack came out of this box or not because we took it out of the box, so we want to return it.
Since the serial numbers matched, it was not a problem to return the pack.
