Product Info

Introduce young explorers to one of the ocean’s most colorful mysteries — the nudibranch! This beautifully restored youth t-shirt features Ernst Haeckel’s 1899 illustration “Nudibranchia”, depicting seven unique and scientifically accurate sea slug species, known for their intricate shapes and vibrant patterns.

This design took many hours of careful digital restoration to revive Haeckel’s fine linework and subtle detail, preserving the vintage character while enhancing its visibility and color clarity for print. The result is a wearable science illustration that’s both educational and artistically stunning.

Printed on the Gildan 5000B Youth Classic Tee, this shirt offers thick, durable cotton with a soft hand-feel — built for active kids who love the sea, science, or anything that wiggles.

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.
