Begin with the commercial system, not a bag of references
A mixed accessory inquiry becomes easier to manage when the buyer first explains the collection. Identify the customer, selling channel, product families, visual theme and destination context. Then list the components that support that system: perhaps a neck label for identity, a sleeve patch for recognition, a decorative transfer for the garment face and a removable charm for a bag.
This overview does not replace individual specifications. It tells every participant why the components belong together and which details should remain consistent. Teebling can use the charter to frame development conversations while separate component sheets record construction, dimensions, artwork and application requirements.
Shared brand rules create coherence. Separate SKU approvals create control.
