Each size set is packaged in its own labeled zip top baggie, and all the sets were in another zip top baggie. There were no instructions, but that's probably a liability issue. I'd hope you did some research before jumping into this. The oil that came with it was fresh and does as intended. Lube up well! Acrylic can get stuck easier than metal or bone, etc. The oil is important with all tapers, but I feel much more with acrylic. My little droplet stopper in my oil bottle didn't work, so I had to pull it out. The tapers are sturdy and are easy to use. The plugs work, but the smaller ones can be finicky to clean just due to size. I have not had the issue of losing the rubber rings like others have. I've not stretched large enough yet to use the tunnels, so I can not comment outside of they are easy to manipulate and would seem easy to put in and take out. This is a great set and is priced well for what it is.
