Kệ Giữ Chai Dầu Gội/Dầu Xả

This is a bottle holder I made to make sure I don't have to shake my bottles to get the shampoo/conditioner to the bottom of the bottle. It's great because it also clears up space on my shelf. This only works with this shelf: https://www.amazon.com/gp/product/B09KXFH6FN/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

I plan to add a way to stick it to the wall soon.
