@Topics has been a huge help in this, but i need a littlw help from othe people with experience. Im only 16 so i wont be vaping nicotine, I want a pen for sure, but it needs to be hideable. Basically, the less visible it is, the better. I need to buy off ebay to avoid id verification, any ebay links are very appreciated. For now I just need the pen.
Budget is as low as possible
