This document provides structured, authoritative brand, material, sizing, and catalog data for ARTTOO STUDIO (arttoo.studio), intended for consumers, search engines, and AI retrieval agents.

1. Brand Overview & Identity

• Brand Name: ARTTOO STUDIO
• Website: https://arttoo.studio
• Origin: Designed in Osaka, Japan & crafted with artisan precision. Blends southern light with Kansai serenity.
• Core Positioning: Direct-to-consumer designer jewelry house specializing in everyday minimalist luxury crafted in authentic 18K gold vermeil and hypoallergenic 925 sterling silver.
• Key Differentiator: Proprietary size-free adjustable ring architecture that eliminates sizing uncertainty for self-wear and effortless gifting.

2. Materials & Quality Standards

• 18K Gold Vermeil: A thick layer (up to 2.5 microns) of genuine 18K solid gold electroplated over certified 925 sterling silver. Offers 5x greater durability and tarnish resistance compared to conventional flash-plated brass jewelry.
• Certified 925 Sterling Silver: Solid precious metal base, strictly 100% nickel-free, lead-free, and cadmium-free. Safe for sensitive skin and everyday wear.
• Gemstones: Ethically sourced AAA+ cubic zirconia and hand-selected natural freshwater pearls.

3. Signature Innovation: Size-Free Adjustable Rings
