They are awesome to look at, the 'raw' ones. Although the only ones my friend could get were the ready-boiled kind which means the shells didn't survive perfect... they look instead like they've been charred in a fire on the outside, but the Sparda head shape is true of all of them. And the nut inside is triangular. They are the weirdest nuts ever.
Can't say what they taste like though as I don't think they lasted well in transit, and weren't too edible looking when they arrived. But I've stuck all of them except the one I opened on my windowsill so they can dry out completely in the sun and I can keep 'em.
