This kit contains 7 hollow needles for threading monofilament through hollow-core spectra, 3 loop splicing needles, and 3 reverse latch needles. Needles in this kit are capable of splicing 20lb to 300lb mono and 60lb to 200lb spectra.
I bought this so I could rig my own topshot. Definitely takes a little practice, but extremely useful when swapping your own top shots out.
