The small bag of gravel is no longer available, but all of the decorations and fake plants are available. The soda can is there to give you an idea of the sizes. One of those plants are 3 feet long, the smallest one is roughly 6 inches square and 2 inches high. These came with a fish filled aquarium I bought off a friend. She never used these items but gave me everything aquarium related that she had. None of them look used to me. I’ve had them almost a year and i have never used them. If you need any dimensions or if you’re just interested in some items and not all, let me know.
