We use only Gildan Tees and all our designs are made right here on site in our shop. Each purchase is made to order using our vinyl cutter to cut the design out of t-shirt vinyl and then we heat press it. Heat transfer vinyl wears very well and last much long than screen print.

This listing is for a Unisex T-Shirt with WHITE print. We offer many different color shirts and we also offer different color prints as well. If you are interested in a different color shirt, style of shirt ex: hoodie, long sleeve, tank, etc. Please contact us for pricing through the Request Custom button.

Please allow 5-7 Business days before your shirt is shipped. Normally it will be done in half the time, but 5-7 Business days to be safe.

First & foremost - Do not get the backing paper wet!
- Clean the surface
- Peel the paper backing, making sure the decal stays stuck to the transfer tape
- Place the decal flat on the surface with transfer tape side up and smooth out the bubbles using a plastic squeegee or a credit card will work in a pinch.
