This is the newest iteration of the classic Cotton Mix by FibreFreaks which is now discontinued. It's a ~70/30 mix of cotton and cellulose.
If you've tried both 100% cotton and rayon wicks then this is essentially a custom blend between those two materials.
Considering it is odourless food-grade cellulose, any 'strange flavour' described in other reviews is likely from the oils in their skin which have been absorbed by the cellulose.
(To the 2 star reviewer below who incorrectly stated this product contains Silicone [which is used in sealants etc] IT DOES NOT.
Rest assured this product contains food-grade Cellulose, which is a completely different material!
Furthermore Fibre N Cotton is 70% cotton, 30% cellulose..
Cotton Gods is 100% cotton and comparable to Cotton Bacon Prime)
If you liked the absorption of rayon wicks but preferred working with cotton, then try this product!
