The contents of the box should convince you enough to consider the kit. In my products, I have some with over 183 pieces of sewing accessories and others with just 33 pieces. However, the larger number shouldn’t be used solely as the basis to buy; it depends on the intended purpose of buying this kit.
To repair just a hemline or a seam, you need not hundreds of tools. But if you are into sewing projects, then getting a large kit is a way to go. Just choose wisely because other tools may turn out to be useless in your basket.
