Thank you for viewing. I've put dried lavender from my garden in an old glass medicine bottle. I shake it and smell it when I sleep with it by my pillow; it smells like lavender and hay. It's difficult to take out when it gets old, but you can put whatever you like in it. The bottle isn't clear; it's a dull, sepia color, a color that shows it's old. There's some cloudiness that won't come off. It seems that glass from around the early Showa era (pre-1945) contained uranium, and it fluoresces under a black light, but I don't know the details. Please check the images. Please understand and accept that this is an old item from several decades ago.
