From Yo-Yo String Lab, this is the signature string of World Champion, Johnnie DelValle. Ammo is a thick version of Type X with the tension tweaked to JD's preference. It's the softest, and the added weight is great for whips, slack play and trick binds. It's "slackalicious!" This string is a bit thicker but don't let the size scare you because underneath its large and powerful exterior is a soft and well natured string that will obey your hands movements down to the toughest whips and air binds.
'Ammo' comes fully loaded containing 50 strings which come out one-by-one for whenever you're ready to reload.
