No, I think it'd be better to have just one listing with a larger quantity. When a buyer goes to your shop, they don't want to see the same couple of listings being repeated.
If you have the same item with some variation (different color, scent, etc), then I think it would be good to put up a separate listing, but the image should be different, so it doesn't come across as the same item.
Hope this helps. Happy New Year! :)
