Just bought these, arrived late and was broken when i pulled it out.
this is a fantastic idea, however this item needs care as they can apparently break in storage, there fragile, can fall apart if u pick up a tower, or even be so tight it requires force to separate.
Paizo is unresponsive to emails and i'm yet to be acknowledged, let alone compensated for the faulty item.
i hope i'm a rare case of this. this item would be beyond amazing during a battle
Edit: just recieved an email from paizo. they are shipping out a replacement for me. fantastic :)
