The Zeyiyer keychain set features 30ml bottles made from flexible polypropylene, a material choice that offers high chemical resistance for various soaps and sanitizers. Unlike rigid PET, this material is designed to handle more repeated squeezing, making it a good option for high-viscosity gels. The transparent walls allow for easy monitoring of fluid levels.
The design includes an integrated molded plastic loop for the keychain attachment. This connection point is part of the bottle body, ensuring the bottle stays with the clip during normal movement. The flip-top cap provides a standard friction fit and includes a removable silicone ring designed to help maintain an airtight seal when the cap is fully closed.
At a dry weight of approximately 12 grams, these bottles add negligible weight to a backpack or keychain. While the polypropylene is resilient, it is best to avoid over-tightening the cap, as this can sometimes cause the silicone gasket to "bunch," which might affect the seal. These bottles are a practical choice for everyday carry where lightweight portability is the primary goal.
For a set that includes both the bottles and specialized neoprene holders for extra decoration, the Iaca 5-Pack Keychain Set provides a different variety.
