It is not verified fact and states no Hermès rule. Each boutique and country works differently and practices change. These are general observations shared without commitment. We do not claim that pre-spend exists or that any amount is required. Collectors describe bags going to established clients who buy over time, come back and build a relationship with their boutique. No outcome, offer or allocation is predicted or guaranteed.

How to read these figures
In these reports the bag asked for moves the ratio: the Mini Kelly sits higher than the Birkin 25, Birkin 30 and Kelly 25 and the few Birkin 35 reports sit lower. Collectors describe the same pattern in their discussions: the most requested sizes ask for more, larger or less requested sizes for less.
Each figure mixes markets, boutiques and years. Reports with two models in one request, or without a size, stay out of this table and remain in the overall median. Collectors who were offered a bag write more often than those still waiting, so every figure here leans low.
Color is not measured yet: few reports name the color that was asked for and most name the color of the bag offered. Future reports will record the request itself before any figure by color is published.
