As a customizer, I am always looking beyond the usual outlets for usable parts.
1/18 Archive on Facebook posted a pic of a box full of figures and one stood out (I copied it with the figure below as an example) as it had beautiful translucent fairy wings. He said that they were from a Dollar Tree doll. Apparently they were sold a while ago as only an out of the way DT had any left, but I snagged all 10 that they had.
These little dolls utilize the same type and size peg system to attach the wings that is used by most 3.75"/4" lines including "Fortnite", "G.I.Joe", "Vitruvian H.A.C.K.S", etc. use to attach backpacks so they are compatible without any modifications.
I have had plans to make warrior fairies for my fantasy world for quite a while but lacked decent feminine wings. Now I have some, and in a few different colors no less. Ideally, I would like to find 2 more to have an even dozen, but am happy with what I found today.
The dolls themselves will go to a coworker that has a little girl on Monday.
