Skulls Unlimited International, Inc. is the world's leading supplier of osteological specimens and creator of the #BoneBox subscription. Each BoneBox includes a mystery skull, collectible animal trading card, unique animal item or art piece, promotions, and exclusive discounts.

Specimens are carefully prepared using dermestid beetles, whitened, and degreased. BoneBox items are "A" or "B" quality with minor imperfections.

The value of each BoneBox exceeds the subscription cost. All specimens are authentic animal bones, not replicas, including skulls, teeth, bacula, claws, and more.

Our BoneBox plan guarantees no duplicates within ten boxes. Due to wildlife export restrictions, BoneBox is only available in the lower 48 states, Alaska, and Hawaii (excluding U.S. Territories, APO, and FPO boxes).
