Classic Biohazard Symbol Stencil

The Classic Biohazard Symbol Stencil paints the biohazard trefoil the way it appears on real warning signs: three crescents around a small solid center dot with thin bridges. It gives an authentic, industrial look to any project.

Use it for warning signs, industrial decor, lab and workshop walls, Halloween props, apparel and DIY craft projects. Cut from durable, reusable 14 mil Mylar for crisp, clean lines, made in the USA.

Frequently asked questions

What does the size mean?
The size is the longest side of the design. The Mylar sheet is about 1 inch larger, so there is a border to hold and tape down.

Can I reuse it?
Yes. Rinse it with warm, soapy water after each use, let it dry flat, and store it flat.

How do I get crisp edges?
Tape the stencil down, use very little paint, and dab or spray in light coats instead of brushing across the edges.

Does it work on fabric?
Yes. Use fabric paint, place cardboard inside the shirt or tote, and heat set the paint as the paint label says.

Where is it made?
It is cut in the USA by Stencil Stop, a small team known for fast, friendly service.
