Biodegradable Water Burial Urn for Ashes | Floats Then Dissolves | Cruise Approved, Certificate Included

Which size do I need?

• Large (11.5″ × 8.5″ × 3.5″) — holds up to 6 lb of ashes. Fits a full adult ceremony.
• Medium (8.5″ × 6.5″ × 3″) — holds up to 3 lb. For a child, a partial amount of adult ashes, or a larger pet.
• Small (5.5″ × 4″ × 1.5″) — holds 8 to 10 ounces. For an infant, a pet under 15 lb, or a keepsake portion.

The average adult produces approximately 5 to 7 pounds of cremated remains, so the Large is the right choice for a full adult ceremony. If you are unsure of the weight, the crematory can tell you. If you are between two sizes, choose the larger one. See the full size guide.

• Material: GreenKraft cotton-based paper and plant fibers; tissue-paper flower, natural jute cord. No plastics, metals or toxins.

• In water: typically floats for approximately 30 seconds to 2 minutes before sinking, when used within the recommended ash-weight limit. Weight is what matters, not volume: filled past the recommended maximum, the urn sinks sooner. The ashes bag dissolves within 1 to 2 minutes. Complete breakdown of the urn varies with water conditions.
• Works in: ocean, lake, river, and earth burial.
• Cruise ceremonies: accepted by most cruise lines for ceremonies at sea; confirm with Guest Services in advance. The included certificate is the document they ask to see.
• Air travel: travel with the filled biodegradable urn is not recommended because it is fragile and not airtight. We recommend transporting the ashes in a separate container suitable for air travel, then filling the urn shortly before the ceremony. See our guide to flying with ashes.
• Not for: long-term display or storage at home (the urn is designed to break down); keeping ashes in a humid place before the ceremony; carrying ashes on a flight.
• Made by: Pachamama Tributes, a small family business. Ships from West Palm Beach, Florida. Orders are processed within 1–2 business days; free shipping within the U.S.
• Reviews: 56 reviews, 4.88 average.

Not releasing everything?

Most families don't. You can return most of the ashes to the water and keep a small portion at home.

The Songbird keepsake holds about 1 cup — a portion, not a full adult amount. Matte white, plant-based, and it reads as a sculpture on a shelf rather than as an urn.
