Sticker Residue on New Loppers — How Do I Get It Off Fast?

I just bought a new pair of loppers, and they came with a sticker wrapped around one of the handles.

I’ve spent the last 30 minutes trying to get the sticky residue off, and I’m only about a quarter of the way there. It’s driving me crazy.

Does anyone have tips or tricks that can save me an hour or more of picking at this sticker? I’d love a faster solution!
