The DIN18 Screw Cap with Tamper-Evident Seal and Vertical Dropper (item RGB02C2B004-200) from Calaso is a professional-grade closure designed to deliver both product security and accurate dispensing. Crafted in black HDPE (High-Density Polyethylene), this screw cap features a DIN18 II thread and integrates a tamper-evident Type II ring, ensuring consumer confidence through visible proof of first use. The insert is made from natural LDPE (Low-Density Polyethylene) with a 2.0mm orifice, engineered to provide smooth and consistent dosing of skincare, wellness, and personal care formulations.

With its ribbed collar design, the closure offers improved grip and handling, while the sleek black finish gives a modern and professional appearance that pairs seamlessly with clear or tinted glass bottles. The 2.0mm vertical dropper orifice provides a more generous flow, making this packaging solution especially well-suited for slightly more viscous serums, oils, and active concentrates. Its compact size, measuring 15.9mm in height and 22mm in diameter with a weight of 3 grams, ensures a secure yet discreet fit for premium formulations.

Engineered for precision and reliability, this tamper-evident closure reflects Calaso’s expertise in closure technology. The combination of HDPE for the cap and LDPE for the dropper insert guarantees durability, chemical resistance, and long-term performance, while ensuring an enhanced end-user experience through accurate dispensing and safe packaging integrity.
