I was getting concerned with the dye from the mouth coils I normally use (the 2 top name brands) and
so decided to go for a plastic one even if it cost more. I phoned Penguin before buying as I wanted
to get enough to last at least a few months and I wanted to get an opinion before spending $150.
They assured me these coils were good quality and I took their word for it.
They are very good
coils. I would even say excellent. They are very long--as long as I would ever want them, they don't
pull apart, they are bright, they unravel smoothly, and there is no fear of consuming some dye that
comes from who know where and what.
