What are Gunpla?
Gundam Plastic models, Gundam Plamo, or Gunpla are model kits depicting the mecha machinery and characters of the fictional Gundam multiverse by Bandai. These kits became popular among mecha anime fans and model enthusiasts in Japan and nearby Asian countries beginning in the 1980s.
The name Gunpla derives from an abbreviation of "Gundam plastic model" phrase, since most kits are made of plastic.
What do the Scales mean?
SD
Super Deformed or SD kits as many know it, are the smallest in our list. Recognized by their big heads and deformed body proportions, SD kits are very beginner friendly and are recommended for children.
Though they are not as posable as the other grades, there is a charm to them. SD kits are very affordable.
HG (1/144)
High Grade (HG) are the most commonly built kits on this list. They're easy to build, and there is a wide variety of HG kits to choose from. These kits can easily be spotted by the HG moniker found on the corner of the front box art. These kits have more articulation than SD units, which gives it more options for poses. They're 1/144 scale make them the perfect size for collecting and displaying.
RG (1/144)
Real Grade kits or RG as the moniker on the box indicates, are fairly new to the Gunpla community. Introduced in 2010, in celebration of the 30th Anniversary, RG kits focus between the skeletal inner frame of Master Grade's, and the size of an HG (1/144). RG kits have more detail, like colour separation, and articulation to give a more realistic approach; they also come with a hefty number of decals, RG kits are great for builders who want to keep within the HG size but want more out of their kit
MG (1/100)
Master Grade (MG) are 1/100 scale kits. Master Grade kits differ from HG with their size and detail. MG kits utilize the inner skeleton, which help its articulation and sturdiness. Of course, MG kits have more technical parts compared to HG kits, but all that detail pays off when the kit is finished, Due to their size, detail, and pose-ability, MG kits are considered a favourite amongst Gunpla builders.
PG (1/60)
Perfect Grade (PG) kits are one of the biggest kits available on the market, and their 1/60 scale definitely stands out amongst any Gundam collection. Not only do you get a fantastic model kit, but the box they're packaged in are also beautifully designed. PG's come with a number of parts, which make these Gunpla look extremely detailed - from finger movement to articulation; expect to spend a weekend or three building one of these kits.
