These terminals come in a nice divided box to keep everything organised. Unfortunately, when using quality crimping tools designed for insulated terminals ($20 Titanium Crimps and $60 Astro Crimps), the terminals easily slipped off the wires. Even after adjusting each crimping tool for the tightest crimp, the terminals separated from the wire with a slight tug. Crushing the terminal with wire cutters resulted in a secure fit, but I wouldn't want to do my wiring that way. After trying dozens of creams, I happily threw them in the trash to pick them up from the store. FWIW, YMMV.
