Do the Neocash items I buy last forever?

The term of an item will be displayed in the item detail when you click on it. Most items will say "N/A", meaning they never expire. There will be some that do list an expiration term, such as 180 days, for example. This means the item will be automatically removed from your inventory/closet 180 days after you purchased it. Be sure to check the expiration term of all items before making a purchase!
