Gundam Special Add-Ons: Caletvwlch Feder

If you have the Transient Gundam, then this is a must have. However, I find the idea of what is, from the looks of it, either an energy construct, or a holographic weapon-thingie, to be a bit out there.

That being said, I did order this (two sets, in fact), just so I can outfit my Transient Glacier Gundam.
