This is a CORTIS penlight, definitely official. It has been used once. * Includes the bag, but the bag's condition isn't great, so consider it a bonus. * The batteries have been removed for storage, but if you prefer, I can ship it with the batteries removed, or I can include new batteries before shipping. ■ As other sellers of authentic items have mentioned, counterfeit goods either have a sticker-like label on the outside or the text is printed on the surface of the tube. Authentic ones have the text printed inside the tube, not like a sticker. Besides the obvious fakes with misshapen "C"s, some have a raised print on the outside, or stickers, and the text on these is strangely shiny. You can tell the difference immediately when you see the real thing, but it's hard to tell from pictures, so please be careful. Functionality confirmed. Immediate purchase is OK. * Will be shipped with bubble wrap and waterproofing.
