you will need to provide mini's for the 2 skins involved as they are both unpriced to make sure that the sale would cap at the 450 key b/o.

since the 2 skins don't have any other recent sales, it would be best to leave this unpriced for now until those can be mini'd.

https://backpack.tf/profiles/76561198019254407#!/compare/1649462400/1649548800 - looks to have sold for 395 keys + Purple Confetti Cotton Head (cotton head will need a mini) but the sale should be below 450 for sure

once the cotton head is mini'd a flat value based off this sale should be okay to give this a price excluding your sale here
