The color of the items you receive may vary slightly from the way they appear here. We strive to present images whose colors match the actual items as much as possible, however, colors are affected by the settings of the monitor they're viewed on, so differences are unavoidable in some cases. There may also be differences in dye lots or finishes.

*Some items with the same color name may be in different dye lots across items, so please purchase a small quantity first or check with us for more info.*
