"This lightweight unisex / men's tank top features an image of a Puffin in a Winter Hat that's screen printed by hand in eco-friendly ink. I personally hand draw each of my unique designs. I expose the art onto a traditional silk screen. Then I screen print each piece by hand with love in my home studio. It's a workout! Ink color (white or black) is as shown in each sample picture and is based on what looks best for the particular graphic and t-shirt color combination. I use eco-friendly, water based inks. They don't require chemicals for clean up. And the screen print design lasts forever, through many, many washes and wears! The muscle shirt is made from soft, lightweight fabric and is a comfortable, unisex style. I purchase from suppliers like Bella and Canvas, American Apparel, and Nex Loose Tank, Muscle Shirt, Knit Dishcloth, Mens Tank, Graphic Tank Tops, Hand Draw, Muscle Shirts, Screen Printing Designs, Men's Tank
