My titanium straws measure 3/8″ in diameter and are available in 9″ and 12" lengths. The oversized 12" long straws are great for larger jobs where extra length is needed. These ti straws are strong enough to be hammered through a coconut! I can sharpen the tip on one end if you request it. These work great for stroking fires as well. Weight: 9" - 31 g. 12" - 38 g.
