Rubber boobs are cool, the real problem is how poorly implemented they are across all coomer figures
>BFB Nicee
only the cleavage is rubber, surrounded by a solid plastic bra, sculpted as a uniboob. All you can do with them is press inwards with your thumb, has no give, making the feature useless. Mooka did not fix this, only changing the plastic pair to silver to make it a color swap gimmick instead.
>Transform element Blackarachnia
boobs are flexible plastic for the transformation, resulting in an ugly orange color.
>Megami gears addon boobs
Squishy due to them being made hollow, chest connector fits inside the hollow space, making them solid and eliminating the gimmick. Completely surrounded by molding flash that will look ugly any way you cut it.
>1/6 seamless figures.
Entire body is made of rubber, meaning that the breasts are flexible as a side effect of the material, but it isn't really that great because the rubber is made durable for the joints.
>4P Flametoys windblade
very small chest sculpt, hindered further by the weird monoboob. I bet you could cut them to be separate like the original kit but it doesn't seem worth it.
I was so excited when they said that they were going to give her new boobs, I expected a larger plastic pair, you are better off buying the model kit and modding them yourself. I'm totally up for Fembots to have weird coomer features, it takes advantage of the fact that third party figures are not controlled by Hasbro, but they have to be designed from the ground up to implement it or it comes across terribly.
>separate the boobs into two individual parts/shapes
>Make them large enough to actually make use of the flexibility
>paint the figure in a finish that will match well with the eventual color of the rubber,
>Include plastic as an option
The only successful use of rubber is that one japanese guy on twitter that made Z-Cup boobs for his Megami Device figures that literally bounce when you shake the toy
