Scientific brushes, also known as soft pens, ink pens, dual-purpose pens, water pens, water pens, and black-out pens, are an evolutionary version of the brush. It is a writing tool that contains water-based ink in the barrel and continuously supplies ink to the nib through gravity and capillary action. Therefore, no ink is needed, and you can write as long as you open the pen cover, and it is also convenient to carry.
