I can tell by the stones what company put this out, LOL. Heres whats not great/missing:
1) No wire end crimps or crimp tool, in the pic. For sealing off ends of a necklace neatly, you need both.
2) The metal findings - pins and jump rings - are utter crap quality from that maker. They are super stiff, and the jump rings are almost always mis-cut. Not the biggest deal, but youll struggle more than necessary to get good quality work done. You sure wont be effectively using that jump ring tool on jump rings you have to reshape.
3) No round-nose pliers. Those pins? Youll need to learn how to make a loop to close the other end, and connect it to something else. You can do a poor job with regular jewelry pliers, but you wont get pretty, professional-looking results, or learn good technique.
4) Crap-quality tools. Can you use or learn with the couple pliers provided? Sure. Will you hate them? Probably. Good pliers have an integrated set of metal spring pieces that pop your tool open by default. You have ever do much less hand strain and frustration that way. The tools pictured here look like the super-cheap kind where the spring steel isnt integrated, but just shoved down inside very stretchy, often loose handle covers that slip off at times. That causes you to get the spring pieces misaligned so they actually will catch sometimes so you cant close the plier until youve fixed it for the umpteenth time, or even just fall off altogether and have to be fixed (again and again).
So, should you not buy this at all? Nah. But, Id look for a good set of tools probably in short order after you get some practice, and realize that in a pretty short amount of time youll realize how bad some of these components are when you buy actual decent-quality parts.
