Four full silicone listings
Ervin and Shona occupy the 168 cm group in the Vivant Aimi collection. Calum and Isla sit at 169 cm. All four are labeled full silicone in that collection. Start with that common material description and use the exact product link to distinguish the offers that fit your preferences.
Check the weight and width too
Shona’s page lists 31 kg and an 87 cm hip measurement. Isla’s lists 39 kg and 100 cm at the hips. The listed heights differ by only one centimetre. Those other figures are more relevant when preparing storage and handling. Ask for carton dimensions and the weight of the specific configuration.
Compare the photographed finish
Save the main image and note the pictured head, hair and finish on each listing. Ask the seller to confirm that those features are part of the same configuration and to identify any optional styling. Comparing product images under different lighting is easier when you have a neutral reference for each choice.
Make the quote comparable
Send the same destination and ask for a written total and the same set of weight and shipping figures for each model. If the seller offers a similar alternative, give it its own line. Keep the original quote as a reference so you can see exactly which part of the configuration or delivered total changed.
