(Pisces is at line 2, colum 2, Libra is at line 6, Colum 6 on the normal inventory)
What are these itens and what are they used for?

Temporary skin appearance. You'll get the cloth (appearance only) for like 30mn. Depending on the box you have it can be glod cloth, surplice, god cloth or even the Gold Saint appearance (with the skills but not the power)

Thanks, that was really bugging me out
