Hello ZeroSins, thanks for your questions. n_n
1. The wig is about 40cm.
2. We use a white spot light when taking product photos to show the wig details, so the actual wig color will be a bit darker than the photo, the effect is just like you put it outdoor under the sunshine.
3. We need about 4-6 days to prepare this wig for you, so if you order it now and use UPS shipping, it probably will reach you within 2 weeks after order confirmed. :)
