    I forget which month this set was, but it was one of the 2018 limited runs. It's a blem, but I'm not sure where the blemish is. It's brand new and has lived in the box since purchase.

    This is a limited run builder set from Aero Precision. I don't recall which month this set was sold, but it is from 2018. The set has never been assembled into anything and has spent its time in the box. It is listed as a blemished product, but I haven't found the blemish.
