Some warnings are posted for safety.

This one is posted because containment has already failed.

The Do Not Feed The Tribbles Tee is a ridiculously fun sci-fi warning label for anyone who knows that one cute little problem can become a full-blown crisis very, very quickly. The design features a rugged containment sign with bold industrial typography, hazard-striping, warning icons, blinking red panel lights, and an alarming number of fuzzy little troublemakers climbing over, around, and behind the barricade.

It is cute. It is chaotic. It is absolutely not under control.

The best part is the contrast: a serious security-style warning sign surrounded by happy, multiplying fuzzballs who clearly have no intention of respecting protocol. The Security Level 7 panel and Containment Breach Likely warning make it feel like official shipboard signage from a situation that has already gone sideways.

Printed on the premium Next Level 3600 tee, this shirt delivers the soft, lightweight comfort and modern retail fit that make it an everyday favorite. Crafted from ultra-soft ringspun combed cotton, it is breathable, durable, and ready for sci-fi marathons, conventions, comic shops, game nights, or any environment where snacks should be monitored carefully.

Do not feed them. Seriously. It’s too late.

Our suppliers provide the measurements. There might be a discrepancy of up to 2 inches (5 cm) in product dimensions.

A useful tip! Compare the measurements provided in this guide with a similar product you own by measuring it yourself at home.

A Length

Start the measurement at the top edge of the tee, right beside the collar (at the Highest Point Shoulder), and extend the tape to the tee's bottom.

B Width

Begin measuring at the seam right below one sleeve, stretch the tape across to the corresponding seam under the other sleeve.
