[Kuretake] ZIG Art Brush Sand

The special brush tip allows for lines of varying thickness, tailored to your preference. Its water-based pigment ink enables beautiful effects like blending, color mixing, and gradients, making it ideal for illustrations or coloring. AP certified, it's environmentally friendly, safe, and non-toxic for peace of mind. Precautions: It is recommended to store the pen horizontally to prevent excessive ink flow. Always cap the pen tightly after use to avoid the tip drying out. Please use with care, as ink may be difficult to wash out if it comes into contact with clothing. Please note that this brush pen is a disposable product and cannot be refilled.
