Buy RS3 Potion flask
Description
The potion flask is a large glass flask in RuneScape 3. It holds up to six doses of most potions, including juju and perfect juju potions. A normal vial only holds four doses, so a flask gives you two extra doses in one inventory space. This helps a lot on long trips like bossing or Slayer tasks, since you can carry more potion with less room.
Flasks are filled by decanting potions from vials. The flask breaks and is destroyed once it is empty. Combination potions cannot be stored in a flask.
Making your own flasks takes work. You need level 89 Crafting to blow one from robust glass. Robust glass comes from red sandstone, which can only be mined once per day and needs level 89 Mining. You also need to finish the quest As a First Resort to use the robust glass machine. Buying flasks skips all of these daily limits and skill requirements.
The potion flask is a members only item. It is tradeable and noteable, and it stacks when noted. It weighs only 0.03 kg, so it will not slow you down. Filled six-dose flasks with tradeable potions can be traded on the Grand Exchange.
