Bag Sampling Process: From Sketch to Bulk (Wholesale Guide)
Published: August 24, 2026 | 8 min read
Sampling de-risks a bag order through staged approvals: the proto sample validates the design, the pre-production (PP) sample locks materials and construction, and bulk follows the approved PP. Typical timeline is 5-7 days for stock-based custom, 15-30 days for full development. This guide maps the milestones wholesalers should require.
