### ⭐⭐⭐⭐⭐ Great product
*by C***N on April 15, 2020*

Great product, it’s difficult to find metric screws in the US. Good assortment with multiple options! Only problem I found was during shipping the panels that separate the sizes must have come off and when the item arrived, the majority of the screws were mixed up and thrown together. Not a big deal just something to be aware of if you need a specific size
