M.S.G Weapons & Parts
Kotobukiya's first-party line of "Modeling Support Goods" is full of excellent choices for builders looking to get the most out of their plastic model kits. Because the MSG lineup uses the same 3mm peg & hole system present throughout the Kotobukiya brand family, it is easy to combine partial or complete sets with other items in your collection to a limitless extent. How far can your imagination take you?
