How to use

Ensure the pen is designed to accept SXR-7 format refills.

Usage recommendations

Store refills horizontally or capped at room temperature away from direct sunlight and extreme heat to preserve ink quality. Replace the refill when ink becomes faint or intermittent to maintain consistent handwriting. For best results, use on standard paper; avoid prolonged contact with water as ballpoint ink is not fully waterproof.
