What materials are used in OPM Graff products, and how do they feel?

OPM Graff streetwear is crafted in London using premium, heavyweight cotton fabrics for a soft yet structured feel. Every item is designed for both durability and comfort, with exclusive graffiti-inspired prints that stand out. Expect quality finishes, breathable fabric, and a luxe hand-feel in every piece from the collection.

How should I care for my OPM Graff graffiti-inspired clothing to maintain its prints?

To keep your OPM Graff streetwear looking fresh, machine wash cold with similar colors and turn items inside out to protect the iconic graffiti-inspired prints. Use a mild detergent and avoid bleach. We recommend air drying or tumble dry on low heat. Always follow the care instructions on the garment label for best results.

How can I be sure my OPM Graff streetwear is authentic?

All authentic OPM Graff pieces include official branding tags and exclusive London-origin designer details. To ensure you receive genuine OPM streetwear, purchase only through our official website or authorized retailers listed on our site.
