Concave Stylus

A concave stylus features a tip that is inwardly rounded or concave, designed primarily for embossing Braille onto various materials. Its distinctive concave shape aids in producing clear and distinct Braille dots with minimal pressure, facilitating the creation of accurate Braille characters. However, due to its unidirectional nature, this type of stylus can only be effectively used in one orientation for Braille writing tasks.
