The whole pen tube is made with continuous spiral concave-convex twist molding process. The special curved texture greatly increases friction when holding the pen, effectively preventing slipping during long writing.

The top of the pen cap is equipped with a detachable white rubber thermal eraser, which can directly rub and erase wrong handwriting without extra eraser tools. The push-type pressing structure controls the extension and retraction of the nib, effectively avoiding ink leakage and nib damage caused by losing the pen cap; the internal spring has stable elasticity and is not easy to jam after long-term use.

It is specially designed for students to correct homework mistakes, draft writing, note sorting and hand account marking, supporting custom logo printing and large-batch OEM customized wholesale.
