Situational, but mine was 50m of CAT5e cable, a bag of plugs, and a crimping tool. I finally eliminated the "but what if we move the router" spool of excess cables behind the furniture.
For anyone wondering this isn't a good idea if you're color blind.
Just buy patch cords in the equivalent length. They will be better built than and you won't waste hours of your time, and a shit ton of copper.
Source: Thought 5 years IT experience and 100ft of Ethernet would be enough to get it. After 2 weeks of frustration - I had 1 cable that worked and I had to buy a tester just to speed up the 'Did I do it right? ' bit. Complete waste of time.
Passthrough crimps are way easier, but you're absolutely right. I now get solid core to run inside the wall and connect to a keystone jack, then premade (usually Monoprice) patch cables from there. Not only is it easier and more durable, but it looks way more professional.
