They are handmade from solid lava stone, directly from the Vesuvius. We will post photos and video of processing and extraction of the stone.
The dice will be tested to be random and the holes will be perfect. The photo shows a test and is not completely finished. This is an handmade product and lava stone is really hard to carve, but we are working to do it more accurately we can!
You have to add $10 to your pledge for the worldwide shipping. We will send dice from Italy (Vesuvius) where they are made.
Unfortunately kickstarter doesn't allow more than one pledge, but you have two options:
1) You can add your new pledge amount to your actual pledge and notify this action to us with an email on kickstarter.
2) You can set up a second Kickstarter account linked to your same Amazon payment account and then make a second pledge.
