Manufactured from cosmetic-grade, BPA-free plastics for safe contact with skincare and topical products. Typical construction: clear PET or PETG jar body for excellent clarity and chemical resistance, with polypropylene (PP) screw caps for secure sealing. Materials are chosen to meet general cosmetic packaging standards; always verify with supplier certification if you require specific compliance (e.g., FDA food-contact statements or cosmetic-grade documentation).

1. Clean jars before first use: wash with warm soapy water and rinse; air-dry. 2. For sterile products, sanitize using recommended methods (e.g., 70% isopropyl wipe) and fill in a clean environment. 3. Fill jars to a safe level leaving clearance for the lid. 4. Close caps firmly to ensure an airtight seal. 5. Label each jar with product name, batch number and expiration for retail or samples.

Ideal for small-batch cosmetic makers, skincare entrepreneurs, estheticians, pharmacists compounding topical ointments, craft producers of lip balms and body butters, product testers, and anyone needing clear, reliable 100g screw-cap containers for cosmetics, ointments and travel-size packaging.

Not suitable for high-temperature sterilization methods that exceed the material’s heat tolerance. Avoid solvents or aggressive chemicals that may degrade plastic. Store jars away from direct sunlight and excessive heat to preserve product integrity. Keep lids tightly closed to prevent contamination. If using for sterile medical applications, follow appropriate sterilization and regulatory guidance. Dispose of responsibly following local recycling guidelines.
