Q: one of the reviews states that human fetal bones are included; is this true? what are the recommended ages for these boxes?Asked by Meaghan R., December 2022

Skulls Unlimited International, Inc. answered...December 2022

That is false. Bonebox subscriptions will never contain real human products. There is currently a large array of items from bats to domestic rabbits, from raccoons to turtles. If you have interest in purchasing human items we recommend that you go to the skulls unlimited site. Bonebox is for elementary school and up. Every skull comes with an educational fact card to learn about what you've received! We are partnered with the Museum of Osteology with the information provided in the Bonebox!


Q: Hey I was wondering where your specimens are sourced from?Asked by Becky K., August 2022

Skulls Unlimited International, Inc. answered...August 2022

Thank you so much for reaching out to us and asking. This is a question we get a lot and are happy to elaborate further.
We do not condone and will not support the poaching of animals, nor do we approve of destroying an animal solely for the purpose of gaining an osteological item. Our suppliers and their sources obtain osteological material from natural & predator deaths, road kills, food source by-products in exotic regions, legal hunting & trapping operations, and from attrition in zoological gardens. All natural bone specimens are legally and ethically obtained. Suppliers World Wide send skulls that would otherwise be discarded or destroyed, as they are collected. You can be assured of, and take comfort in knowing that your purchase conserves treasures...


Q: Do you receive duplicates of an item? Multiply skulls of the same animal or will it know to include a new item?Asked by Sarah B., February 2022

Skulls Unlimited International, Inc. answered...February 2022

There are currently over 20 species that we ship out but the guarantee for no duplicates of skulls from species you've been sent expires after 10 months. After 10 months, it is possible to receive duplicate skulls of the same species due to the ethical sourcing of materials that we maintain.


Q: Can you ship to the UK?Asked by Holly L., January 2022

Skulls Unlimited International, Inc. answered...January 2022

Unfortunately, Bonebox is only available in the United States. We do not ship to APO addresses or out of the country because there are real bone products inside Bonebox, it would require coordination and additional fees with customs and the country's version of fish & wildlife protection.

I was so excited for adding more stuff to my bone collection.... however I have got rat skulls and coyote claws EVERYTIME. And I'm a little upset about it. You get 2 items every month and it's always coyote claws and rat skulls.

I got a rat skull and a buffalo tooth. Beautiful pieces, but was hoping for something more? It is the Time of Covid, so I get it.

I got an email advertising a sale on their website. I browsed through the items for sale. I was shocked and disgusted to see that they sell real human fetal bones. Adult human bones I can somewhat understand as I hope those individuals chose to donate their bodies. Unborn babies, however, I would think that the families that donated their child's bodies probably did so for research into why the baby did not survive and not for a company to sell. I'm sure many will say it's ok because science/biology but morally I can not get past this and I will never do business with your company again.

Overall pretty okay

This was my very first bone box, I really enjoyed it. I got a domestic duck skull and a bonus alligator ear bone. I gave 4 stars because my duck skull was broken on the bill.. but due to the fragile nature of the product it's understandable. Not a great display piece but still cool none the less.

Not a lot to get excited about

This box was ok...... only got 2 items, little disappointing, thought for the price you'd at least get some small related type items along with the bigger pieces..... the quality on the 2 things that were received are good just wish there was more to enjoy...... I'll give it another month and see if this is something I'm going to continue.....

Shark teeth?!?! Are you kidding? Sharks are slaughtered left and right, giving shark teeth is SO INAPPROPRIATE!!! One rodent skull + shark teeth?!? Shame on you! How dare you contribute to shark death. This is so unethical. I wanted to add to my bone/skulll collection but this so not the right way
