How can I get my targeted laser pointer pen

Hey, guy,
last week, my friend bought a mini laser pointer,it is gorgeous, I want to
buy laser pointer for the coming meeting presentation , I don’t need the most powerful laser pointer, my friend suggest me to get it at such store could by buy wholesale Electronics, but although there are so many laser pointers for sale, but the prize not reasonable, so I would like to shopping one
red Light Laser online, you know the
red Light Laser, I think the
100mW red Laser could raise the attention of attendants, blue light laser pointer is ok.
Could you tell me how can I get it? Thanks
