Why Choose Pearl?




Mariposa is characterized by a unique new swing top, derived from historical canning jars from the USA. It has a completely removable glass lid for easy filling and cleaning in between. Glass lids, glasses and hangers are designed to be as economical in terms of material as it was technically feasible in order to save valuable resources. The force to open and close is minimal thanks to the absolutely flat vertical pressure distribution.



For thorough cleaning and multipurpose use, you can easily disassemble the Mariposa closure.

Simply push the round metal wire upwards to release pressure on the glass lid and move both the round and glass wire towards you where it says WIRE.

Remove the glass lid, take off the rubber ring and you’re ready to clean!

To reassemble, just replace the rubber ring and glass lid and push the round and straight wire directly above the glass top.

Ensure that for closing the jar, the straight wire needs to fit into 2 of the 4 recessed points before pushing the round wire downwards.

Having worked in the glass packaging industry, we know first hand the endless benefits of working with glass as the core material in our Pearl products.

Glass not only offers high resilience allowing for frequent reusability but is also made from all-natural ingredients and is fully recyclable for more environmentally friendly storage and packaging solution.

Our glass designs are made to each be capable of serving multiple functions for various applications, enabling multiple uses and longer life cycles.

Experts often describe glass as a frozen liquid that has no pores and is therefore very unique. As an inert material, glass is also non-reactive, airproof and waterproof making it an excellent protector of food providing low migration that is likewise effective in preserving taste and flavour, without compromising taste.

For timeless aesthetic and décor, glass also allows us to create beautiful, multipurpose designs fit for every occasion and classic addition to every household.
