This is a 520nm laser pointer with a nice brass host, activated by a side button. The beam is very bright at night and easily visible indoors, even during the day! Our pen style laser pointers are built to feel nice and heavy in your hand - the build quality is MUCH better than your typical pointer. Beam specs are excellent - with good divergence, and with less of the annoying box reflection compared to other green and blue laser diodes. These can be powered with either 2xAAA batteries or 1x10440 and a dummy battery. Batteries should be inserted with the positive side facing the front of the laser!
