What material are the t-shirts made from?

Most of our t-shirts are crafted from 100% organic cotton, ensuring maximum comfort while promoting sustainability. This means you get soft, breathable fabric that's gentle on your skin and better for the environment. On top of that, the organic cotton is durable, making your t-shirt last longer through numerous wears and washes. For a different style, we offer all-over print t-shirts made of polyester, providing vibrant and lasting prints for those who love a pop of color in their wardrobe. So, whether you prefer the natural, sustainable feel of organic cotton or the bold, lively designs of polyester, we’ve got something for everyone.

How should I care for my DipaliZ t-shirt?

Caring for your DipaliZ t-shirt is simple and helps keep it looking great: Wash Cold: Turn your t-shirt inside out and wash in cold water with similar colors to prevent fading and maintain the print quality. Gentle Cycle: Use a gentle cycle to avoid excessive agitation, which can cause wear and tear. Mild Detergent: Opt for a mild detergent to preserve the fabric's integrity and color. Avoid Bleach: Steer clear of bleach or any harsh chemicals that could damage the material and design. Air Dry: For the best results, air dry your t-shirt. If using a dryer, choose a low heat setting to avoid shrinking. Ironing: If needed, iron your t-shirt inside out on a low heat setting. Avoid ironing directly over the print. With these care tips, your DipaliZ t-shirt will stay comfy and stylish for a long time!

Can I return or exchange a t-shirt if it doesn’t fit?

Absolutely! We offer a hassle-free 30-day return and exchange policy. If for any reason you're not satisfied with your purchase, you can return or exchange it within 30 days. Just make sure the t-shirt is unworn, unwashed, and in its original condition with all tags intact. Once we receive the item, we’ll process your request promptly, so you can shop with confidence. Your satisfaction is our priority.

Are there any special care instructions for printed designs?

Yes, caring for DipaliZ printed designs requires some special attention to keep them looking fresh: Turn Inside Out: Always wash your t-shirt inside out to protect the printed design from rubbing and fading. Use Cold Water: Wash with cold water to maintain the color and vibrancy of the print. Gentle Cycle: Opt for a gentle cycle to reduce wear and tear on the fabric and print. Mild Detergent: Use a mild detergent free from bleach to prevent any damage to the design. Avoid High Heat: Skip the dryer or use a low heat setting. High heat can cause the print to crack or peel over time. Skip the Iron: If ironing is necessary, make sure to iron the t-shirt inside out and avoid direct contact with the printed area. With these steps, your DipaliZ printed designs will stay sharp and stylish for many wears to come!

The story behind this design

The joke only works if the typography commits, so the lettering is drawn in the manner of a 1980s video-nasty title card: heavy, slightly warped, with drips that start thick and taper. The mathematical expression itself is set cleanly, in a textbook serif, which is where the tension comes from. Bone white and a single arterial red are the only colours on the black ground.

Frequently asked questions

Q: What does the design mean?
A: It stages one divided by zero as a horror scene. Dividing by zero is undefined in mathematics, and the artwork treats that as something to be afraid of.

Q: What colour and sizes are available?
A: Black only, in unisex sizes S, M, L, XL, 2XL and 3XL.

Q: What is the tee made of?
A: Heavyweight cotton, as stated in the product title.

Care

Machine wash cold inside out and tumble dry low. Do not bleach and do not iron directly on the printed area.
