Product Info

Curious minds meet curious fish.
This youth t-shirt features Ostraciontes, the horned boxfish, as drawn by Ernst Haeckel in 1899 — a standout species known for its boxy shape and comical horns. Part of the Box Puffer family, the longhorn cowfish is a marine oddity that delights kids and scientists alike. Haeckel’s highly detailed scientific illustration brings this quirky creature to life from multiple angles.

Printed on the Gildan 5000B Youth Classic Tee, this shirt is built for real-world adventures. It’s thick, soft, and durable enough for outdoor learning, science fairs, aquarium visits, or just proudly nerding out at home. Whether your child dreams of marine biology or just loves weird sea creatures, this tee makes ocean education fun and wearable.

Why Made-to-Order is Better for the Planet 🌎

When you choose made-to-order products, you're making an eco-friendly choice that helps reduce waste and pollution. Traditional mass production results in millions of unsold garments ending up in landfills or being incinerated, releasing harmful toxins into the air.

By only producing items when they’re ordered, we eliminate excess inventory, reducing textile waste and lowering the environmental impact. Plus, this sustainable approach conserves resources by avoiding overproduction.

Your purchase supports a smarter, greener future—one where fashion is made responsibly and only when truly needed. Thank you for making a difference!

As every item is made specifically for you, we usually can't accept returns but if you have any issue with your item, contact us we will be happy to help in whatever way we can.
