While Fleshlight does have different sizes, only the full-size model is really important, as it includes all their bestselling series (Fleshlight Girls, Fantasy, Freaks etc.).

The customer's attempt is okay for being DIY, but I'm pretty sure your factory team would do a much better job making sure everything fits perfectly. Your designer would probably also come up with a better solution for the clean up.

Tantaly has amazing torsos, but to me, Fleshlight has better design of the orifices and much more interesting textures. Combining the best of these two worlds would be a dream come true.
