S>Spectrum/Dual Blade Mask Anvil Service - Free

mind if i post some of my stuff i have up for the same deal?

You can post/pm what items you want the appearances on. But remember I am not "buying the anvil".
I am receiving your Anvil to put my item appearance on your item.

Same here, and not to be rude but how can we know you wouldn't keep the item?

You are not being rude. I would ask the same question as well.
In respect to why I would do it for free, is because I dislike how people are Selling Fusion appearances as opposed to it being done with just the Anvil.
I wouldn't keep the item because I have better items respective of Eye and Face accessories, and I wouldn't want to tarnish my reputation here at SP.

With that being said, you can always consider cheaper random items as opposed to high-end items for fusion.
