Using this stationery set is super easy. You can use the A5 notebook to write down your thoughts, stories or school notes. The pencil is great for rough drafts, and you can sharpen it with the included sharpener when it gets dull. The pen is perfect for final writing. If you make a mistake, just use the eraser. And the sticky notes are handy for leaving reminders. When it comes to maintenance, keep the wallet in a dry place to prevent damage. Avoid getting the stationery wet as it may ruin the notebook pages and affect the performance of the pen and pencil. Also, be gentle with the sharpener to make sure it works well for a long time.
