Boho Pom Pom Yarn Flat Sandals

I love these bright sandals. Such fun beautiful colors. Flat open sandals. In marker 41 has been scrawled on the ext soles. Not sure if a ref to size as I think they are closest to 8 (my size) maybe 8.5 I wear 8 and think they are a good fit. Preowned. Dawlance (?) stamped. Hippie ethnic festival
