Hi everyone! Today I’m doing a test to see if my oldest thermal polishes still transition. I see the question asked often, “How long do thermal polishes last before they die and stop transitioning?”. No one really knows the answer. There are some variables that will help them last longer, store in a cool dark place is the big one. Many brands will not mail thermals during the hottest months so they will not get burnt from the heat during transit.
So this collection of thermals is my oldest, let’s see if they still work!
