Reusable 3ml Cartridge Pen | 0.25mg–1mg Adjustable Dose

Precision-engineered reusable injector pen designed for use with standard 3ml cartridges. Spring-driven mechanism delivers consistent dose accuracy across a 0.25mg to 1mg adjustable range, with audible and tactile feedback at every increment for confident dose-setting.
