Custom enamel manufacturing for business projects.

OEM is a suitable starting point when your organisation already has artwork or a defined design direction that needs to be prepared for manufacture. ODM is relevant when you need an original concept developed or an existing design direction adapted. Both routes still require agreement on the product structure, enamel process, fittings, quantities and supplied form. Tell us what is already decided and what you need help to develop; the route can be discussed from there.

Yes. We support original development from a business brief and adaptation of an existing design direction. For original work, share the intended use, product type, brand references and requirements. For an adaptation, identify what should remain and what needs to change, such as colour, outline, attachment or presentation. The available reference material, development scope and intended deliverables are discussed for the project before work is agreed.

Artwork is an important input, but it does not define every manufacturing decision. We also need to discuss the intended size, detail, enamel finish, metal appearance, reverse, fittings, quantity and packaging. Artwork or sample review may identify points that need to be clarified or adjusted. Production arrangements are discussed against the agreed product reference and scope, rather than assuming that a supplied image is already a complete production instruction.

Yes, a project can be discussed across these product families. A shared visual theme does not mean that each item has the same construction or supplied form. Pin backs, keychain connections, medal suspension and charm hanging points need their own decisions. Please list each product, design or version separately, including whether quantities refer to individual pieces or complete sets, so that the scope can be defined clearly.

No. OEM and ODM describe the design starting point; soft and hard enamel concern the product finish and manufacturing approach. The surface effect, detail, metal boundaries, fittings and intended product need to be considered together. Both finishes can be discussed within an OEM or ODM project. The appropriate production route is defined for the design and finish rather than using one sequence for every product.

Agree the relevant design version, dimensions or size direction, enamel and metal finish, fittings, quantity by design or version, and the supplied arrangement. Artwork, sample references and any open review points should be clear to both parties. Target timing, packing and project-specific review requirements also belong in this discussion. Changes to these inputs may affect the work that needs to be assessed, so they should be identified before arrangements are confirmed.

Start with the product features and reference that matter to your order: appearance, colour areas, metal boundaries, dimensions, reverse, attachment, version and packing. Share the checks and supporting information required by your purchasing process. Factory and quality information can be discussed on a project basis, with the actual materials and review scope confirmed for the project. This does not imply that a particular certificate, test report or unlisted approval is already available.

Yes. The scope can include enamel components or assembled products, together with the presentation and packing discussed for the project. State whether you need individual pieces, sets or components for further assembly, and describe any backing card, protection, identification or outer-packing requirements. The product, fittings and packaging need to be reviewed as one supplied arrangement; they are not assumed to be identical across all orders.

Our in-house scope includes tooling, metal forming, enamel colouring, polishing, electroplating, assembly, inspection and packing. Green Frog Supply is operated by HANGZHOU FORTHRIGHT TRADE CO., LTD in Hangzhou, China. In-person visits and video factory reviews can be arranged by appointment, and project-specific factory or quality information can be discussed. See Our Factory for the work-area and review information. Generated factory illustrations on this website are clearly labelled and are not actual factory photographs.

Share your company, product types, design starting point, available artwork or references, estimated quantity for each design or version, target market, intended use, packaging and target timing. Mark any decisions that remain open. Development scope, product construction, finish, fittings, sampling and supplied form all affect the discussion. Quantities, costs, schedule, design deliverables and any requested rights or exclusivity need to be confirmed for the particular project; they are not a single standard promise for every enquiry.
