Here is the listing. It is very high quality, and is among the best tasting I've used. I bought it after very little drunken research, in a whim. I am very pleased with it so far.
Ah man nah its everywhere https://www.amazon.com/dp/B00VHA3ZXQ/ref=cm_sw_r_cp_awdb_imm_7XN7RWHNYWE6JNPDPMAQ?_encoding=UTF8&psc=1
Not familiar with it but if you read one of the Q&A's regarding if it's organic, one of the answers said they contacted Shiseido and they replid "all natural cotton fibers and bleached for purity". Most folks use organic unbleached this or this (there's plenty of reviews from folks using them for wicking, lol)
If it's just roundwire you're looking for, use TEMCo's official amazon store. For cotton get Muji (if you're in NYC, Boston, or Portland, you can get them in Muji retail stores), Labo Puffs, or these slivers. If you want claptons go to wireoptim (not sure if their New Years sale is still live), coilturd or coilclout for fancier stuff like aliens.
I wouldn't get wire from Amazon unless you're getting roundwire stuff like Kanthal from Temco's official Amazon store... Check wireoptim for wire spools and pre-wrapped coils (also has tools and Cotton Bacon if you want that, otherwise organic cotton visit your local Muji if you in NYC, Boston, Portland or get it from them online or from Amazon).
I suggest getting Muji. Puffs Organic Cotton is also a good choice, but I found Muji has less of a break in and the taste seems cleaner.
I like this, but beware, it's a lifetime supply...
