Ballpoint Cwj Mem Cov lus tsim ntawm Daim Npav Daim Npav Tag Nrho yog "hollow out", uas tshawb txog kev sib raug zoo ntawm sab hauv kev ua haujlwm thiab cov tsos ntawm cov khoom. Lub hollow slender tau milled rau ntawm lub cev los qhia cov hlau Refill sab hauv. Cov duab tsim qhov chaw tsim nyog rau tuav tus cwj mem, uas pom qhov sib npaug ntawm kev zoo nkauj thiab tib neeg engineering. Tsis tas li ntawd, Tag Nrho hnyav 19 grams, uas muab kev nkag siab zoo ntawm kev tuav los txhim kho nws cov neeg siv kev paub.
