Crystalised equals it got cold....warm it up and the crystals disappear
I have bought this product a lot of times, love it. I received one set where bottle A was completely crystallised I was really peed off as you can imagine. Then I googled it and found out that I could put the bottles in warm water....hot not boiling and the crystals will melt away. Just warm it and give it a shake...back to clear fluid and runny in no time. I just wanted to post this as a guidd due to others mentioning itnin their reviews, its winter resin doesn't like the cold.
