If you want more details, mechanics, and an inner frame skeleton to show off, then the Master Grade kit is for you! They are the next level up from HG kits, and while more expensive, it's all worth it due to the kit's level of detail, including gimmicks, mechanics, and some "dry-rub" decals that will greatly enhance your model's expression.

Master Grade kits only come in 1/100 scale, which is typically around 18 cm tall. Some recent MG kits are much larger, like the MG Sazabi Ver. Ka and the MG Unicorn Full Armor. MG kits have the "MG" abbreviation on the box, which is colored gold, so you won't miss the marking. The size of the box varies depending on the number of parts, with the largest being from models like the MG Sazabi Ver. Ka.

The details in an MG kit are where it starts to get very interesting and amazing. The big difference between an HG and an MG kit is that MG kits have an internal frame or skeleton mechanism, where you attach the armor pieces one by one, just like a Samurai warrior would when preparing for battle. Color variation and separation of the armor pieces are also well-designed. Most MG kits do not need additional painting, as they already look fantastic right out of the box like HG kits. Some MG kits also include some LED light-up features.

One of the best things about MG kits is applying the "dry-rub" decals, which are standard additions to MG kits. They really make the model seem realistic and increase the level of detail. It takes some practice and technique to apply them to a kit, but it's worth it. If you want a crazy amount of decals to put on your model, you should consider buying an MG Ver. Ka. Kit. MG kits with a "ver. Ka." extension in the model name are redesigned by Hajime Katoki, and he really likes a lot of decals. You won't be disappointed by the quantity of decals that ver. Ka kits have. EW kits also include a lot of decals, as EW kits are also redesigned by Katoki.

Master Grade is recommended for the enthusiastic Gundam modeler/hobbyist who wants more details on their models. MG kits require more effort and work, but the reward is worth it.
