Every seashell is a gift from the ocean, and I pack each one with the care it deserves, ensuring its safe journey to you.
Preparation Time: I will carefully wrap your seashells in recycled paper and twine within 1-3 business days, making it feel like a personal gift from the sea.
Shipping Method: I use reliable standard shipping and will provide you with a tracking number, so you can follow your shell’s journey.
International Orders: For shells traveling across oceans, please allow a little extra time. Sometimes customs checks can extend their journey.
The ocean never creates two identical shells, making the one you receive truly one-of-a-kind.
Damaged in Transit: If your shell is damaged during its journey, please contact me within 24 hours of receipt with a photo. I will immediately send a replacement or issue a full refund.
Not as Described: I do my best to represent each shell accurately through photos and descriptions. If you feel your shell is significantly different from what was described, please contact me within 7 days, and we will find a thoughtful solution.
A Note on “Change of Mind”: As each shell is a natural, unique item, I cannot accept returns or exchanges due to a “change of mind.” Please review the photos and dimensions carefully to ensure it’s the perfect “ocean companion” for you.
We are deeply committed to sustainable and ethical practices. All our shells are sourced responsibly—never from live-shelled creatures. We support marine conservation efforts and maintain transparency about our sourcing practices.
Plococidaris verticillata belongs to the cidarid sea urchins, a primitive group known for their thick, blunt spines rather than sharp needles.
These spines often host tiny marine organisms, making the urchin a living micro-ecosystem on coral reefs.
