Write down the base configurations
Kanadoll lists Chiharu at 166 cm with a 36 cm shoulder width. Imogen is listed at 172 cm with a 38 cm shoulder width. These figures describe the individual product pages. Ask the retailer whether the measurements include the head and which specification applies to the exact version on the quote.
Read the unpacked weights first
The Chiharu listing gives 36 kg standard and 29.5 kg after reduction. Imogen is listed at 44 kg. Those figures are a starting point for handling plans. Keep the reduced Chiharu weight associated with its specific option and ask which figures include the head and any selected hardware.
Check the boxed sizes independently
Chiharu lists a 156 by 42 by 30 cm carton and a 41 kg package. Imogen lists a 160 by 42 by 31 cm carton and 49 kg packed. Measure the tightest part of the delivery path using carton measurements, then ask for confirmation for the actual package before dispatch.
Confirm the options on both quotes
If you are considering both models, ask for a delivered quote for each with the head, material and finish written out. Request information about the current weight option and included accessories. Retain both quotes with the source links so differences in price can be traced to the configuration.
