Each sand brick ball contains 1 raw stone, 7 types in total, shipped randomly, which one will appear? There are also 3 types of sandpaper (A-coarsest, B-coarse, C-finest). Follow steps 1 to 4 to grind the excavated raw stone and feel its hardness! Directions: ※To avoid rubbing the tabletop and inhaling dust, it is recommended to prepare a mat, newspaper, a cup filled with water, a rag, a mask and goggles before use. •STEP 1 ➡︎To avoid scattering during the process, please lay down newspapers first. •STEP 2 ➡︎Use props to carefully dig the raw stone to avoid damage to the raw stone; •STEP 3➡︎ After the raw stone appears, use a brush to remove the remaining sand and soil, and then wash it with water. •STEP 4 ➡︎Use sandpaper to grind the raw stone! ★Key point: First dip the raw stone in water, and then perform "water grinding" while it is wet to prevent high temperature generated by friction with powder! Use sandpaper A-coarsest and start grinding from the uneven and sharp parts of the surface. When the ground part does not feel rough and feels smooth overall, you can clean the stone and wipe off the moisture; then use "Sandpaper B-Coarse". After the rough shaping and smooth surface, clean the original stone again and wipe off the water. Touch the surface condition with your hands, and finally grind it with "sandpaper C-finest"! ※When switching to finer sandpaper, in order to avoid the coarse powder from the previous grinding from damaging the surface of the original stone, please pay attention to the following precautions when switching to sandpaper: 1. Remove the powder remaining after grinding; 2. Clean the original stone and wipe off the moisture. •STEP 5 ➡︎Confirm the hardness of the rough stone! Is the raw stone easy to grind or difficult to grind? Compare it with the picture on the left of the instruction manual to see its hardness! -------------------------------------------------- ★Warning: Contains small objects, not suitable for children under 14 years old. ●Combination contents: sand brick ball (including 1 raw stone), small brush, small shovel, 3 sheets of sandpaper (A-coarsest, B-coarse, C-finest are marked on the back), Japanese instruction manual ●Packaging size: about 8*9*8 cm in width and 244 g in height (including packaging).
