Need a large number of laser pens

Hello! Did anyone here wholesale laser pointer pens online before such as a powerful green laser pen? I think it is difficult to find nice green laser pointers for sale at an excellent online shop. As I plan to start a business on wholesaling different kinds of laser pens mainly Wholesale Blue Laser in the market, a nice shop offering cheap Blue Beam Laser is in need. Besides, some people suggested me to sell 100mw laser and the widely used red light laser pointer, which has a large market recently, especially the red laser pointer keychain. So can any of you recommend a reliable online shop for me?
