Spiderman toddler sandals size 12

selling these spiderman sandals because my son has grown out of them. they're in pretty good shape, one of the heel lights has stopped working and apparently he stepped on playdoh at daycare and crammed it into the tred on the soles of the shoe, but other than that it's in very good shape. he wore socks with these sandals so the interior is very clean. purchased these at target for 30, asking 20 but reasonable offers will be considered.
