The eggs comes in a plastic carton of six. Just pop open an egg and find a sleeve inside. Each egg has a different texture inside so you can try a variety of different sensations. These are disposable so you don't have to worry about clean-up, but some reviewers say you can reuse if you'd like.
Promising review: "Bought these for my boyfriend. Each one comes with a packet of lube (and the lube is SUPERB. It does not have a strong smell, lasts for a long time without having to stop and add more, and leaves NO sticky residue afterwards like most other lube). He loved them all and can't decide on a favorite, and they've ensured quite a lot of quality time. This is also the cheapest I have seen for this set compared to other sites, and it shipped very quickly." —Lisa D
