Review on Mini Skater Tapping Micro Screws Assortment by Jesus Olsen

This product works best on very thin woods. These are smaller wood screws than most people will likely ever see, about 1/2 the size of the screws that hold the hinges to the kitchen cabinet hinges. The shortest can attach a miniature loop to a 1/4" thick piece of wood and won't come out the back. The box itself is about the size of a mid-sized smartphone and twice the thickness of a phone. Of these and metric sizes are in listed in the product description, but it would be helpful to see a generic item next to the box to get an idea of the size. The spilling/mixing mentioned by others was not an issue for the package I received.
