Great for keep the clay moist for longer periods of time and very portable. The water crystals were surprisingly useful and great for this, but a fair warning, the crystals can eventually dry out, even when kept closed in this vault as it's not 100% air tight (especially if you have to keep taking/opening them out of it for projects). I don't think they intended it for a "reeeaaally" long term/permanent storage which was why I didn't take a star off. So my only advice is to check on the crystals every so often to be sure they are still moist and to remoist them if needed if you plan to use it to store your clay for as long as necessary. But it's certainly a great option and I don't regret getting this with the smaller vault storage. I'm not sure how long it took my crystals to dry out, but I'm guessing it's within 1-2 months, at most.
