Thank you for understanding. -Care Instructions- The item has been washed once during the dyeing process. If you wash it with other items, the indigo should not transfer, but it would be better if you wash it separately once or twice. After that you will be able to wash it safely with other items. If the item rubs hard against white clothing, the indigo may be transferred. Please be careful.
