I appreciate the info. I will keep a close eye on them and if they flake off at all I will remove them. I haven't even heard of anyone having any issues with these, specifically, as these are one of the few actual recommended artificial branches that I've seen. Usually the issues that I've seen are the branches that have things glued/added to them.
Also, the #1 recommendation is real branches. And with that being said, the bark on real branches can clearly flake/break off, be sharp, etc as well. Those can also get in a chameleons eyes, yet we still use them. So Idon't think there's this much greater danger with flukers vines vs real branches. At least with the flukers vines, we will know when it's time to remove them because we will see the damage on them, if that occurs.
