Prince Lighter Not Sparking

Hi all, first time here but I’ve recently started collecting lighters. My girlfriend purchased this new Prince lighter for me for V-day and it’s stopped sparking. I have been absentmindedly flicking it so my hunch is that I used up the wick, but I’m not sure what kind of wick to replace it with. It’s not a petrol lighter with the cobbing but more like a refillable butane lighter.

Does this need a replacement wick or something else entirely? TIA!
