Gundam Models, also known as Gunpla, are scale model kits based on the popular Mobile Suit Gundam anime franchise. These models represent various mechs, or mobile suits, featured in the series and are made from plastic. They come in different grades, such as High Grade (HG), Master Grade (MG), and Perfect Grade (PG), which vary in complexity and detail. Building Gundam Models is a popular hobby that allows fans to assemble and customize their own mobile suits. The kits often include detailed parts and stickers, enabling enthusiasts to create unique designs. Many builders enjoy painting and weathering their models to enhance realism and showcase their creativity.
