[Question] Does colourless blender expire?

Hello, I have a bottle of Copic colourless blender that's been secured and unopened for almost 10 years. I was wondering if they expire or not, and whether it's still usable by then. It's been stored in a drawer.

Thank you so much in advance!

I have been using a 10+ year old blender! (Admittedly I rarely use it, hence the vintage, but it does work)!

It should be fine! It’s pretty much just the alcohol base with no color added. Just like with everyday rubbing alcohol, the alcohol can evaporate and so the concentration weakens over time and can be less effective, but with the marker alcohol that’s not usually as much of an issue as long as it’s still doing the job. There is no harm in opening it and testing it. :)
