As Krissy said, they're always saved. But it's at the rank skylord ($50) that you get the command /enderchest to access it at any time.
Theres some enderchests u can use (if u arent a skylord) at /warp trade or at /Visit BertBerry for a public enderchest you can use to store your stuff : D PS: You can also use /ec short for /enderchest if u r a skylord+
