Double Blade Precision: Engineered with twin opposing blades, which apply pressure from both sides, guiding force through the pill's fracture point for a cleaner split. Compact & Convenient: Beyond its cutting capabilities, it serves as a mini pill box making it ideal for travel and daily use. Compatability: Accommodates pills up to 0.4" (10mm) in diameter and 0.4" (10mm) in thickness. Designed for hard pills only - please avoid using with soft gels, capsules or any micro-sized pills. Design: Aluminum base that slides open and closed along grooved tracks and a 360-degree swiveling clear acrylic cover. First Time Users: Practice positioning your pill between the splitter blades a few times before actully cutting - it makes a big difference! With a little practice, you'll get the hang of it.
