Ah OK. Its definitely not a special edition one. They looked like water slides at a glance but I didn't look too closely.
The Master Grades in your picture are somewhat heterogeneous when it comes to markings:
- RX-78-2 Ver. 3.0 is all stickers. Something unusual on MGs but it kind of mimics the Real Grade.
- Nu Ver.Ka has a bunch of stickers (reflective for the psychoframe and your usual sensors, dark textured for some black pieces) but the markings are water slides. Something that really isn't that common. Not even all Ver.Ka kits come with water slides.
- Char's Zaku II has the most common combination you'll find in Master Grades: transparent stickers for certain markings and dry transfers for others. Some also have reflective stickers for sensors.
