We offer bone boxes made of the same material as our coffins, namely lightly galvanized steel sheet. Please note that these boxes are not waterproof and cannot be used as airtight coffins. We always keep in stock reduction boxes in sizes 60, 90, 120, 140, and 160 cm. We can make them to your dimensions (in length) upon request. Easy to store, they are stackable when empty, to save space.
