>>9301461They come with a massive lump of molding flash on the boobs which are really difficult to cut cleanly due to the type of rubber. 9 times out of ten you will be left with an ugly hairline around the sides of the boobs. The connectors are made mostly for the Chinese girl kits, and the one made for megami device kits barely work. They are ever so slightly too wide for both the old and new tops. The plastic pegs on the connectors fill in the hollow inside of the boobs, removing most of the squishy-ness seem in the videos. If you are a really good modeler and want to put in the work, they can be fun, but you're mostly going to be better off with resin boobs as far as variety and ease of use.
