Hi I may or may not be in the right section so you'll have to forgive me if I'm not but I got a vtc5 and 4 the vtc5 is about a year old but wasn't really put through much strain as I didn't sub ohm that often back then and the vtc4 is about 6 months ish but was sub ohm'd much more I was thinking of re-wrapping them because I've not used them in a long time but was wondering about the shelf life and if it'll be safe to continue to use them thanks in advance.
