[This is the product link for the one I purchased while in China.](https://detail.tmall.com/item.htm?abbucket=16&detail_redpacket_pop=true&id=19057978054)

Most of the product details are not available unless you log in, so here is [a link of the product from a reshipper](https://www.superbuy.com/en/page/buy/?url=https%3A%2F%2Fitem.taobao.com%2Fitem.htm%3Fid%3D19057978054&htag=pc.en.search.19057978054&nTag=pc.en.search.19057978054). I bought the 200 packets one with the blue-pink packaging, which has 5 different bacteria. It has other varieties purported to have 8, 10, 16, 30, and even [60 different bacteria](https://img.alicdn.com/imgextra/i3/4611686018427382141/O1CN0162y76d1M8DBAdohVV_!!4611686018427382141-0-tbbala.jpg_960x960.jpg_.webp), which sounds dubious but idc since I only bought the simplest.

International shipping might kill the deal unless you buy a bunch. Note that I'm not affiliated with the reshipper or the seller.
