Our M&G Comrade is a 0.5mm fully automatic mechanical pencil that has a unique design that automatically advances the lead as you write or draw, without the need to manually press the lead. However, it features a side button that offers smooth and convenient lead release, as well as the ability to retract the lead back into the pencil which plays an essential role in adjusting the length of the lead to your desired length. This feature, combined with the pencil's fully automatic mechanism, makes it a great choice for anyone seeking a convenient and efficient writing tool.
