I added silica gel packs to my military surplus ammo cans and used about an inch of double sided tape to stick one of these to the inside lid of each can... now everytime I open the can I get an instant visual of how well the silica gel packs are holding up and which needs to be replaced.... works perfect and MUCH cheaper than second guessing and having a can of 308 rust up on you... Review: Works exactly as advertized. I use them in my ammo storage boxes and they provide an excellent indication as to when I need to recharge the desiccant...Plus, these can be brought back to a zero state by heating the card...I just place it close to a bulb and in short order its like new... ## Features - Country of Origin: China - Material: Paper - Dimension: 1" x 2" x 4" - No assembly required ## Technical Specifications | Specification | Value | |---------------|-------| | Product Dimensions | 2.54 x 5.08 x 10.16 cm; 45.36 g | | Part number | HIC3DOT_50pcs | | Material type | Paper | | Power source type | AC | | Manufacturer | Absorbent Industries | | Item model number | HIC3DOT_50pcs | | ASIN | B002YR87RK | ## Images ![Humidity Indicator Card - 3 Dot 30%/40%/50%-50PK - Image 1](https://m.media-amazon.com/images/I/61bPw9e7QsL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by D***L on 1 December 2014* worked well...
