These sort of work….. but are a lot of work for me to use. morning and night. There just is NOT enough bang for my buck and also the whitening power misses BETWEEN my teeth so I feel gel in a tray is the next option or a one time whitening session from my dentist which includes trays and gel for later touching up!

Looks good on!

Color: OFF BLACK 1B

This is a really pretty wig and looks good on. It eventually starts to tangle a little, depending on how often you wear it. Don't sleep in it. It's very soft.
