What is Gundam and what is a “model kit”?
Gundam is a Japanese saga about giant robots (mecha). Bandai’s model kits (called Gunpla) come on plastic runners. No glue required thanks to snap-fit engineering and color-molded plastic. Painting is optional; just cut, snap, and apply stickers or water-slide decals for a great result.
Instructions are universal (step-by-step diagrams). Each part is identified by a letter (sprue) and a number (part), e.g., A12.
Tools: must-haves, nice-to-haves, and what to avoid
| Must-haves | Nice-to-haves (finish) | Avoid at first |
|---|---|---|
| • Fine side cutters (nippers) • Sanding stick/sponge (400–1000) • Tweezers (for small stickers) • Cutting mat or rigid cardboard |
• Panel-lining marker (black/grey/brown) • Precision hobby knife (for fine nubs) • Cotton swabs & isopropyl alcohol • Spray clear coat (matte/satin) outdoors |
• Strong glues (not needed) • Harsh solvents without experience • Paints/laquers on your very first kit |
Safety: always cut away from your hand; ventilate when using sprays; keep small parts away from children and pets.
Build times and difficulty by grade
Indicative times for a complete beginner, building calmly and without painting.
| Grade | Scale | Approx. height | Difficulty* | Typical time | Best if you want… |
|---|---|---|---|---|---|
| HG | 1/144 | ≈ 12–14 cm | ★☆☆☆ | 1.5–4 h | Easy, quick start; huge variety |
| RG | 1/144 | ≈ 13 cm | ★★★☆ | 4–10 h | “Premium” detail in small size |
| MG | 1/100 | ≈ 18 cm | ★★★☆ | 6–15 h | Display presence, inner frame |
| SD | Deformed | ≈ 8–10 cm | ★☆☆☆ | 0.5–2 h | Fun quick build; great gift |
| Mega Size | 1/48 | ≈ 37 cm | ★★☆☆ | 3–6 h | Huge visual impact, simple build |
| 30MM | 1/144 | ≈ 12–14 cm | ★☆☆☆ | 1–3 h | Modular customization & kitbashing |
| 30MS | — | ≈ 14–16 cm | ★☆☆☆ | 1–3 h | Stylized figures, swappable parts |
*Difficulty estimate (1 = very easy · 4 = advanced). Time varies by model and whether decals/panel lining are applied.
Grade guide (what to expect & who we recommend it for)
HG – High Grade (1/144)
Perfect for beginners. Color plastic, fewer tiny pieces, solid articulation, and a massive catalog. Tip: if unsure, start with an HG design you love.
RG – Real Grade (1/144)
“MG-like” detail in HG size. More tiny parts, technical markings, and often an inner frame. Recommended after 1–2 HGs. Patience and tweezers help.
MG – Master Grade (1/100)
Larger size with internal structure and lots of posing options. Takes time; looks stunning even unpainted. A great weekend project after HG/RG.
SD – Super Deformed
Chibi proportions, very quick builds, charming on a desk/shelf. Sub-lines (SDCS, SDEX, MGSD) offer varied detail levels.
Mega Size (1/48)
Towering height but engineered to be simple. Measure your shelf before buying.
Other / special grades
In Others you’ll find Entry Grade (very simple), MGEX (effects/LEDs), Full Mechanics, MGSD and more.
What to buy by profile
- Easiest first step: HG or SD.
- Love fine details & markings: RG.
- Want a “display piece”: MG or Mega Size.
- Want to customize and mix parts: 30MM / 30MS.
Your first project, step-by-step (quick summary)
- Prep the area: good lighting, cutting mat, and a parts tray.
- Read the manual: identify runners (A, B, C…) and the first sub-step (torso/head).
- Two-stage cuts: first cut leaves 2–3 mm; second cut flush to avoid stress whitening.
- Gentle cleanup: use the sanding sponge to remove nubs.
- Dry-fit, then snap: test the fit before pressing until it clicks.
- Stickers/decals: use tweezers; for water-slides, place with a damp swab.
- Panel lining (optional): highlight lines with a fine marker; clean with a lightly moistened swab.
- Clear coat (optional): a matte layer protects and unifies. Spray outdoors and at distance.
FAQ – Frequently asked questions
Do I need paint or glue?
No. Gunpla are snap-fit and color molded. Painting/gluing is optional for customization.
Stickers vs water-slide decals?
Stickers are quick and easy; water-slides are thinner and more realistic but require practice.
What age are they for?
They are model kits, not toys. Recommended for teens and adults. For minors, always with supervision.
Do you ship?
Yes. Fast shipping across Europe. Competitive rates at checkout.
