I'm developing a premium keychain line for my brand, JA • dotyk, and I'm interested in obtaining a quote and samples for a fully assembled charm set. The set should include a polished gold keyring, an engraved logo disc charm (with "JA" and possibly “dotyk”), a gold-tone letter charm, a bright red tassel charm crafted from silk-style thread, and a functional lip gloss charm in a stylish red PU leather case with gold accents. Additionally, we may explore optional charms such as a birthstone charm, mini mirror, zodiac disc, crystal, refillable perfume vial, or a custom initials tag. Please provide details on MOQ, pricing for each component and assembly, sample costs and lead times, along with customization options for colors, logo engraving, and font samples. It's also essential to confirm if you can supply the actual lip gloss, packaging options (like velvet pouches or boxes), and any relevant product certifications. I'm looking for a reliable long-term partner focused on premium quality and branding standards.
