Nicely packaged in a metal box. I used this today to repair two 6mm threaded holes in an aluminum frame bicycle. Hand drilled and hand tapped. Insert went in without any trouble.
This is a great kit that has pulled me thru some tough repairs on internal threads!
Kit comes with the appropriately sized drill bit, helicoil specific Tap (this is not a regular thread sized tap), helicoil Installation tool, and helicoils in several sizes.
This kit is a life saver,Plenty of replacement coils to last a while and everything has its own little slot for storage
