Ready-made shrink film with self-adhesive backing. This helps with the weatherproof fit. The tips are in good condition which helped me finish the wiring. They crimp well with the tool I use. I've found that using 6 ga spade lugs on my 4 ga wiring works better for crimping. I'm not sure if it has to do with the cable size or the lug size. So I honestly can't give 5 stars, nor would I.
