To use this Nanoblock Mazinger Z kit, start by laying out all the 370 pieces. Find the instruction manual and follow it step - by - step to assemble the figure. It might be a bit tricky as it's a level 3 difficulty, so take your time. When handling the pieces, be gentle to avoid breaking them. After assembly, place your Mazinger Z figure on a flat and stable surface to display it. To keep it in good condition, avoid touching it too often as the oils from your hands can damage the pieces. If it gets dirty, use a soft, dry cloth to gently wipe it clean.
