Ossus Tech Fragments Decorations
Ossus Tech Fragment decorations only require Tech Fragments to purchase, but you need to fly to Ossus to buy them from the vendor near where you load in to the planet. There are multiple decoration merchants in this area, but you are looking for the one called Decoration Merchant, a little astromech droid. The others require Reputation with Ossus as well.
Tech Fragments, a type of end-game currency, can be earned in a wide variety of ways, particularly at max-level.
