MASPRO SKYWALLIE U2SWLA20B White Built-in Booster

I had planned to use this, but due to various circumstances, I was unable to use it and kept it in storage.
It is a new, unused item.
I opened the box once for photography.
The outer box is warped.
As this has been stored by an amateur, please only purchase if you understand this.
I will ship it as is in the outer box, covered with plastic or similar.
