SILVERCEL Antimicrobial Alginate Dressing [SILVERCEL dressingNG 4X4] by SYSTAGENIX WOUND MNGMNT

will this pass through airport security since it contains silver?

How many boxes of 10 is there?

What are the instructions for using this product?

Why do the 4x4 of current order(lot# 35759v001)seem thinner than my wound center's same product? why was 1of10 a 50/50 thick thin 4x4?
