While in the Korean supermarket again, I bought another package of xylitol gum, which I thought was Lotte's, but, while it shares a similar packaging format (all in Korean, unfortunately, with no English label sticker), and, as far as I can tell, a similar xylitol content (76% as opposed to 75% for Lotte), the main difference is that these gum pieces are coloured apple green. Not much difference in taste or effectiveness, either. And, again, a similar price (about $2.40). Though, this was the last bottle available, that I could see. I think I prefer the Spry ones, but these are not bad.
