This product is a full wig made of human hair. The hair color is black. Data details: 28cm from the crown Side length: 22cm Front hair length: 11cm. The photos show the wig on a standard-sized mannequin, but there is still some room. You can use it regardless of whether you have your own hair, as it covers your head like a hat. As you can see in the third photo, the hair covers the ears, making it look less like a wig. As it is human hair, it is a wig with a natural look. The size can be adjusted with the two inner belts at the nape of the neck, with three levels of adjustment on each side. You wear it in the same way as a hat. The head circumference size can be adjusted up to approximately 54cm. This product has size adjustment adjusters on the inside at the nape of the neck. It is elastic, so you can adjust the size by hooking the attached hook on the tip to the ribbon inside. The adjustment is possible in three stages on each side.
