Bandai just announced the RG Expansion Effect Unit "Seraphim Feather" for the new RG Wing Gundam Zero EW. This will be a premium set. Bandai starts accepting pre-order today (21st Nov 2014) and expected to be released in Jan 2015.
Check out below the official poster and some photos for this. As I would expect the price is around RM95~105 (similar to the P-Bandai RG Exia Repair kit). Do you think this is a worth kit?
