Monthly Capsule Items are special items that were released at the start of every month alongside Monthly Donation Items. They were sold in the Donation Shop through Toy Capsules. Like Monthly Donation Items, the Toy Capsules were sold in the Donation Shop for the entirety of the month and cleared out when the next month's items are released, never to be released again. This makes Toy Capsules limited in number which, depending on supply and demand, could increase their value over time. The capsules cannot be worn, but rather can be opened to obtain either one of that month's Donation Items, or one of two exclusive, bonus Monthly Capsule Items: a rare and a common. There is a smaller chance that one of the exclusive capsule items will be won. The Toy Capsules cost 300 Luna each, equaling $3.00 (USD), as opposed to 200 Luna for Monthly Donation Items, so it is a gamble to try and win the exclusive Capsule Items.
All past Toy Capsules and Capsule Items can be bought from other users via trades.
The Rare Capsule Item was first introduced November 2008, and the Common Capsule Item in December 2010.
