Packaging
Our glass containers are 100% recyclable, and closures use 50% PCR plastic (varies by availability). Boxes, inserts, and shipping materials are compostable, made with FSC-certified/recycled paper and soy-based ink. Every product also has a plastic-free option and zero-waste refills.
How to recycle
For a zero-waste choice, get a refill—each comes in a glass bottle with an aluminum lid. Swap your old closure onto the new bottle, then recycle the empty glass and lid! If not refilling, wash, remove the label, and recycle the glass. Take apart closures and check local recycling guidelines—small pieces (like closure elements and label backing) can be recycled through PACT Collective or be discarded. All boxes and shipping materials can be composted, reused, or recycled.

This is my first time trying Siren Silk (mermaid milk is my absolute fave, but I thought I would give something else a try) and it's probably what one would expect - silky! I'm enjoying it as part of my nighttime ritual.
