Surcharges rau Customization
Customizations-xws li cov logos tshwj xeeb, txawv teb chaws- cov ntawv nyeem, tshwj xeeb los tiv thaiv- cov qauv hauv qab, lossis cov qauv tsim qauv tsim qauv- yuav tsum tau tsim cov pwm tsim tshwj xeeb. Kev them nyiaj ntau dua 30% siv rau cov khoom me me -batch xaj, whereas loj -batch xaj tso cai rau kev txiav tawm ntawm cov nqi pwm.

Kev soj ntsuam thiab lees txais cov qauv
Cov phiaj xwm hauv nroog xav tau thib peb - tog neeg thauj khoom - cov ntawv ceeb toom kev sim thiab daim ntawv pov thawj tshuaj xyuas cov khoom; cov chaw tsim khoom cov nqi kuaj yog suav rau hauv tus nqi hais. Tsawg-tus nqi, tsis yog- cov khoom lag luam tus qauv uas tsis dhau qhov kev sim no tsis raug nqi li no.

Kev thauj mus los, qhov hnyav ntawm cov khoom, hom tsheb, thauj khoom / tshem tawm, tiv thaiv ntim thiab xa khoom lub sijhawm tag nrho cov khoom thauj khoom thauj, tshwj xeeb tshaj yog rau ntev - kev xa khoom ntawm qhov hnyav loj - loj npog.
