According to my experience, this grommet assortment pack is a great solution for those who require a variety of sizes and types of grommets for their industrial projects. The assortment is quite comprehensive and covers all bases. The quality of the grommets is impressive and they are sturdily built. The only con I could mention is the lack of storage case, but I was able to overcome that with my own storage solutions. Highly recommended for those in need of a reliable and efficient grommet solution.
