This is a 2-pair set of Robocar Poli socks. The size is 15cm to 22cm. It's a very popular Korean animation, and it's also very popular in Taiwan. These were purchased in Taiwan. While they are made in Taiwan with peace of mind, the stitching and other aspects may be slightly less refined compared to Japanese products. They are new and unused, but as they have been in someone's possession, please refrain from purchasing if you are sensitive. They do not have non-slip grips.
