Sorry for the late reply. I wanted to finish the topper and lighten the hair and wash it a couple times before I posted the links or recommended it.
The closure I got was this one: https://www.amazon.com/gp/product/B09TWD2VYX/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1
And that company didn't have bundles at the time I got the closure, so I got bundles here: https://www.amazon.com/gp/product/B01CTMI3OG/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
The hair from both places matched perfectly in color and texture. I don't think there was any silicone coating. And if there was, the hair underneath after washing it off actually feels like virgin unprocessed hair. It lightened like virgin hair. And after washing and bleach-bathing it to a dark brown color, it's still really soft and nice feeling. Unlike when I've washed a premade topper for the first time and it feels nothing like it did out of the box. I think I will be making my own toppers from this hair from now on. I'm pretty happy with it and it saved me a ton of money. Plus I have enough bundles left to make like 3-4 more toppers. So I'll just need to purchase closures when I'm ready to make another. The only thing about the hair is that the ends do look kind thin and stringy when you first get it. But after finishing the topper and cutting the hair it looks great and blends nice with my hair. I just made sure to order it longer than I wanted the finished topper to be.
