How to save ParticleEmitters which go into user's torso?

I want a saving system which will save any ParticleEmitters in a user's profile. These are purchased with points that you gain in-game.

Also, not all ParticleEmitters are equipped at once so in the shop I have you have options to equip/unequip the Emitters.

The saving system as in the player can log out and in at anytime and their items from the previous session will stay.

If you need anymore information to help me with, let me know.

Thanks!
