Buy RS3 Empty cup
The Empty Cup is a simple item in RuneScape 3. Players get it after drinking a cup of tea or a cup of nettle tea. It is a small item that weighs 0.05 kg, and it is tradeable and noteable.
The main use for an empty cup is to fill it with tea. Use it on a tea flask with at least one dose left to make standard tea. Use it on a bowl of nettle tea to make nettle tea, which is needed in the One Small Favour quest. The cup can also be used to make a Guthix rest potion. This needs a bowl of hot water, a harralander, a marrentill, and 2 guam leaves, and it requires the One Small Favour quest to be done.
The empty cup can also be filled to make a cup of hot water, milky tea, or plain water. Players who train Invention can disassemble it too. It gives Simple parts most of the time and Variable components on rare occasions. It is a small item, but it has a real use for quests, potions, and skilling in RS3.
