To use these MiniTech figures, first take out all the resin parts from the package. You'll need some glue to assemble them. Just follow the basic shapes of the figures and stick the parts together carefully. After assembly, you can use your own paint to color the figures according to your preference. When handling these figures, be gentle as the resin parts can break if dropped or squeezed too hard. To keep them in good condition, store them in a dry place away from direct sunlight. If they get dirty, you can use a soft, dry cloth to gently wipe them clean.
