celestron firstscope 114 short

[amateur stargazer]

i currently have the celestron firstscope 114 short, got it a few years ago, but due to northern irish weather, havent really used it, but just wandering what eyepieces would be good, i use the ones that came with the scope, which are ok but i want to see more details, not just the outline of jupitor and its moons, the eyepieces i have i dont know the magnification but they have K25, H12 and H6 written on them, dont know what that means but hopefully you pros out there will. thanks
