They aren't structurally functional and they aren't visible, *but*
they have a purpose... when making a large object, the side holes
ensure that the deepest point of the object is shallower than if the
hole weren't there. This accomplishes two things - the center of the
part cools and hardens faster, plus there's less overall plastic so
the shrinkage factor as it cools is less likely to put a
depression/flaw where it might be visible.
Negative space still has a function.
It's a common thing with injection-molded plastics to consider wall
thickness and body thickness. It's not about "saving a few cents in
plastic", but it is about less effort to get faithful parts.

Cool. I don't know if folks would want to get 20-30 toggles at 15
Eur, but closer to 5 Eur is in striking range
What is the material, BTW?

My memory of all the toggles I've handled (no pun intended) is that
they have a glossy finish, not a matte finish.
