It’s no surprise that this invention was created. In Japan, wet foods and noodles are often served at meals. These splash guards were designed to prevent noodle juice getting into your hair. However, they have never been widely used.

They are still very useful. The guards are made of silicone and perfectly fit your face to protect you from any messy accidents. The guards are not fashionable, so they are mostly worn at home.
