ISO Eris Merch (SFW)

TLDR; where can I find safe for work body pillow/covers/blankets of Eris as an adult?

Specifically, I'm looking for any variety of bedding featuring the grown up version of Eris we're seeing in season 3, with an emphasis that it is not overtly sexualized. I've got an elementary school aged son who is obsessed with Eris, and I'd like to get him something like that for his birthday later this year.

Disclaimer: Before anyone gets up in arms about parenting, I'm not letting him watch the show. He loves sword fighting, and wanted to see cool sword fights in anime. I've shown him clips, and reduced the story down to multiple kid appropriate bedtime stories about various characters.
