I don't think you'll find this anywhere else! I believe it was sold at Comiket before the anime adaptation. Product Description: This is the "Yuru Camp△ Summer Blanket" sold at Comic Market 92 (Comiket 92/Summer 2017). To avoid getting too cold in the shade or in an air-conditioned room... With a refreshing illustration drawn by teacher Afro, this summer blanket is the size of a lap blanket, perfect for summer! I took it out of the bag and stored it in a dark place immediately.
