Premium Material: Made from laboratory-grade PP plastic that resists staining and odors. Sterilizable (boil/steam) and dishwasher safe for repeated professional use. Hygienic Anti-Contamination Design: Each jar features an airtight seal that prevents bacteria growth and keeps products fresh. The smooth, non-porous interior resists buildup of creams and powders for easier cleaning. Color-Coded Professional System: Six opaque colored lids (black/white/pink/purple/green/blue) on clear jars create an organized workspace for makeup artists, skincare routines, or craft projects. Quickly identify contents at a glance. Generous 10Gram Capacity: Each container holds nearly double the volume of standard sample pots (3.8cm diameter × 2.2cm height), providing ample space for creams, serums, or small accessories while remaining travel-friendly. Multi-Purpose Design: Beyond cosmetics, use for storing pills, spices, beads, or small hardware. The wide mouth accommodates brushes and spatulas. Stackable when empty to save space.
