Custom Dental Lab Made Teeth Whitening Tray Kit & 38% Gel !

Kit came in 4 days.. Trays sent out 2 days later to the lab, it came with a prepaid envelope, that was nice! I sent them in... and received them back in 6 or 7 days.. the fit was PERFECT! it is an exact, tight fit to my teeth. When I apply the gel, it automatically spreads around the teeth evenly, which is important so it whitens the teeth evenly.. Overall, i saw at least 6 shades whiter and only took less then a week.I would recommend to a friend, Thanks!
