Description(English)
The traditional ruler is too thin to be picked up from the planar surface; the pencil is easy to roll off the table due to uneven placement. To solve these two issues, we have designed a new multifunctional ruler named “N” ruler, which is easy to pick up and can hold a pencil. With a beautiful appearance and an ergonomic use, “N” ruler can improve the efficiency of users’study and work, and bring convenience to life.
