Ib tug cwj mem yog ib yam cuab yeej siv tes rau kev sau ntawv lossis kos duab, feem ntau yog rau ntawm daim ntawv. Feem ntau cov pas cwj mem yog ua los ntawm hmoov graphite sib xyaw nrog cov av nplaum uas yooj yim rau kev rho tawm. Cov cwj mem feem ntau yog cov ntoo nyias, feem ntau yog puag ncig, hexagonal hauv qhov seem, tab sis qee zaum cylindrical lossis triangular. Lub plhaub sab nraud tuaj yeem ua los ntawm lwm yam khoom siv, xws li yas, flocking lossis ntawv. Yuav kom siv tau tus cwj mem, lub plhaub yuav tsum tau txiav lossis tev tawm kom pom qhov kawg ua haujlwm ntawm lub hauv paus ua qhov ntse rau tib neeg qhia lawv tus kheej.

Tus cwj mem yog ib qho cuab yeej yooj yim tab sis zoo kawg nkaus uas ua tau raws li qhov xav tau ntawm koj chaw ua haujlwm thiab kev kawm ua tsaug rau nws cov kab tsaus nti. cwj mem HB yog tus qauv rau kev sau ntawv txhua hnub. Koj tuaj yeem ua ntau qib ntawm cov hlau txhuas rau ntau yam kev xav tau sib txawv thiab tsim lossis xaj koj tus cwj mem zoo tagnrho hauv ntau yam xim sib xyaw ua ke suav nrog ib kab ntawv thiab ntau cov ntawv sau. Ntxiv nrog rau kev siv cwj mem, koj tuaj yeem muab koj lub logo rau kev txhawb nqa lossis kev tshaj tawm ntawm koj lub npe ntawm tus nqi qis, thov so kom paub tseeb tias cov graphite seem ntawm tus cwj mem tsis muaj tshuaj lom, thiab graphite tsis muaj teeb meem yog tias noj, tib neeg yuav paub lossis tsis paub yuav nco ntsoov koj thaum siv, yog li qhov no yuav yog ib qho khoom txhawb nqa zoo tshaj plaws rau kev xaiv.
