How to store mats, armors...

• 

  On Silan (the place you are when you create a toon): only with the merchants (mats, tools, armores, weapons, jewels...) in the Ranger camp.

• 

  All other are on Main Lands (ML, see Atys map below): Kami's like: Fyros in desert, Zoraï in Jungle or Karavan's like: Matis in Forest and Tryker in Lakes.

Where you can store?

• Merchants if you sell at the max. rate, you'll have a week to take it back - if nobody buy it. On ML, there's hawkers too.
• Mount and Mektoubs: free account can have only 1 Mektoub (or Gubani).
• Apartment (sub account)
• If you are in a guild, you can use GH (Guild Hall is a little bit like Apartment's Guild, but bigger). As member, you can put stuffs in GH, not taking anything. To take stuffs from GH, you need at least to be Officer (or higher rank). If your guild has an OP, you can access GH Inventory near the OP.

And, some players organize Markets (black or mini ones). Check the Forum.
