To use this Pochacco Nanoblock set, start by laying out all the blocks and the instruction guide. Follow the step - by - step instructions carefully to build your Pochacco figure. Take your time and be patient, as the blocks are very small. When handling the blocks, make sure your hands are clean to avoid getting dirt on them. After you've completed your Pochacco model, you can display it on a shelf or in a display case. To maintain the set, store the blocks in a sealed container to prevent them from getting lost. If the blocks get dirty, you can gently wipe them with a soft, dry cloth. Have fun building your own cute Pochacco!
