These are children's T-shirts from a marathon event. All 6 shirts have no back print. Photo 2: Color is black, size is 130. Photo 3: Color is navy, size is 130. Photo 4: Color is lime, size is 130. Photo 5: Color is blue (slightly dark), size is 130. Photo 6: Color is a slightly fluorescent orange. The tag is cut off, so the exact size is unknown, but it is likely 130 (it almost overlaps with the T-shirt in Photo 5, so I believe they are the same size, but please understand that the exact size is unknown). Photo 7: Color is orange, size is S (larger than the others). All have been used, but I don't think they were used very frequently. These are all used, second-hand items, so please consider purchasing them with an understanding of this. Thank you for looking.
