How do you open an armor set from runescape?

"Once it is turned into a boxed set, the only way to convert it back to single components is to have a GE clerk exchange the boxed set for single items. You can NOT right click on a set and use the destroy option to do this. Simply right click on Sets Grand Exchange clerk and once your GE Item Sets window pops up, right click on your boxed set that's in your inventory, and choose Exchange (type) armour set."

As quoted on the following link:

go to the grand exchange clerk right click her/him

click "Sets grand exchange clerk" then right click your set and click "exchange *example*"

then you get your items from it =)

if you want it back as a set.

right click the set that you had and click "exchange *example*" and it will be back as a set.
You open the set by exchanging the components of the set through a clerk at the Grand Exchange.
You Go Too The Grand Extaing And Select "sets"
