The reusable jar that solves the single-use problem — now made in Europe with 100% recycled Wild Glass
Most screw-cap canning jars are made for one-time use. Opening them damages the sealing disc (platina), making the closure unsafe to reuse and creating unnecessary waste.
Luna Preserving in Wild Glass solves this with a smarter, more sustainable design. Our exclusive, patented vacuum-release slot makes opening effortless — without damaging the platina — so you can reuse the closure again and again.
The jar itself is made from Wild Glass — a raw, beautiful material crafted from up to 100% post-consumer recycled glass.
Its naturally occurring bubbles and colour variations are a visual reminder that no new raw materials were used.
Wild Glass production reduces CO₂ emissions by at least 25%, minimises waste, and gives glass a second life — without compromising safety or durability.
Functional, reusable, and beautifully imperfect — Luna Preserving in Wild Glass preserves more than food. It preserves resources.
