Guild Wars 2

I wonder if they can be reused like the Zenit-weaponskins.
I haven’t used the chest from heroic edition yet because i could not decide which char should get the skin, and using it on a lowlevel armor seems like waste if they are so expensive- i assumed it is one-time use. But now that i see that i can get the weaponskin that was reward for achievement-points i wonder if that applies to the armor skins too?

Short answer: yes, gem store armors are one time use.

Long answer See this other thread posted today

thanks, guess i will keep the chest in my bank for saving space unless i can decide. at least i did not use it yet!

No problem! On my second account, my heroic edition chest is securely in my bank as well. no idea where to use it yet.
