Extract $item code from array in k2store - php

Question

I try to extract and to show on the page with echo product code field in K2store cart page (store extension for K2 for Joomla) but without success. The right value is "product_code" or "code" (is the same value): 26910.
Both "echo $item->product_name" and "echo $item->product_id" works, but "echo $item->code" and "echo $item->product_code" return NULL.
var_dump($item) show me this:
