These erasers are super fun to use. You can use them during playtime with friends, or when you need to correct mistakes in your homework. They're also great for collectors to add to their collections. When you get the erasers, you can start taking them apart and putting them back together like a puzzle. Since they're hand - assembled in Japan, they're of high quality. To keep them in good shape, avoid dropping them on hard floors as they might break. Also, don't expose them to extreme heat or cold, as this could damage the erasers. If they get dirty, you can gently wipe them with a soft, dry cloth.
