The Mariposa introduces a unique detachable glass lid for comfortable pouring and thorough cleaning.

Instantly recognisable for it’s traditional feel, our Mariposa Mason Jar takes inspiration from vintage swing-top jars, used in the 60s for preserving home cooked food and boasts an elegant design for timeless usage. Mariposa’s ability to combine a lightweight design with the robustness of a perfect vacuum is a phenomena we at Pearl call the “Butterfly effect”.

The Pearl Mason Jar series features a vintage design as a real reusable jar, measuring indicators and space for your label.
