I have 3 sets (20 light colored and 10 dark colored) of larger water crystals that I got from China. They are glass and are a lot larger than the stock pieces as you can see from the photo. Free to anyone who's interested.
I had to order from China. Got enough for me and my buddy but there were minimum numbers you had to order so that's why I have extra. With shipping from china and the product cost they are very expensive. I'm giving them away as I'm not looking to make any money on these and what am I going to do with hundreds of glass crystals lol. They are a pretty sweet upgrade to the game.
