👕 Size & Fit

Our tees are crafted with a retail unisex fit, designed to provide a modern, streamlined look that fits closer to the body without being too tight. Made from lightweight, breathable 100% combed cotton, these shirts offer both comfort and style. Please note that they may shrink slightly after machine washing and drying. For a standard fit, men should choose their usual size, or go up a size for a more relaxed look. For women, we suggest selecting one size down for a more fitted look, or your regular unisex size for a comfortable, slightly looser fit.

For precise details, check out the size chart next to the size options above 👆.

😎 Keep Your Koioki Tee Fresh

Flip It: Always flip your tee inside out before washing to keep that artwork poppin’.

Wash Cold, Stay Cool: Toss it in with cold water—keeps the fit and the vibe just right.

Gentle Vibes Only: Set your washer to gentle mode. Your tee (and the design) will thank you.

Chill on the Detergent: Use a mild detergent—no need to go heavy, let’s keep it smooth.

Bleach? Nah. Keep that harsh stuff away—no fading or ruining your look here.

Air Dry for the Win: Hang it up to dry for max freshness. If you’re in a hurry, low heat in the dryer works too.

No Hot Presses: If you need to iron, avoid the design. Flip the tee inside out or cover it up—let's keep the art clean.

🌿 Produced with eco-friendly practices

Every Koioki piece is made-to-order using the latest eco-friendly printing techniques, helping us reduce waste and avoid over-production.

Our apparel is crafted in factories that follow strict ethical standards.

Awesome Gift for your Pokemon Enthusiast

Purchased for my nephew who's an avid Pokemon fan. Ordered an Adult Small and it's true to size. Quality and stitching is great. Material is breathable and has stretch so it can keep up with his active nature. Print and coloring holds up through multiple washes (He's already worn it several times since his Birthday). Overall happy with my purchase and would highly recommend brand.
