I used these on one short day hike and decided I like my heavier Black Diamond pole better.  Tips show almost no wear.  Here are the specs:

Lock System : Flip-lock
Length：65cm〜135cm
Weight：150g/pc（excl. Cap and Basket）

Shaft：100% Carbon fiber

Dia of the shaft: 16mm-14mm-12mm
Grip：EVA
Strap：Adjustable strap made of polypropylene.

A new set will cost you $117 plus shipping from Japan.  I am asking $100 shipped.  Not a huge discount but these are going to be expensive to ship due to the length.  Payment via Paypal.  Sorry, no international shipping.
