CH Hanson sells two low-cost accessories to protect and enhance your marking tools: Pencil Armor and Crayon Armor. Although I find it hard to justify spending a few bucks to protect a ten-cent pencil, I’ve held the pencil armor and it does look pretty cool. Armor for crayons, on the other hand, might make more sense since they’re a bit more expensive and fragile.
CH Hanson designed the aluminum Pencil Armor to work with rectangular carpenter’s pencils. The armor only exposes as much of the pencil as you need. You advance the pencil by sticking your thumb into the slot and pressing forward. The Armor also has a clip so you can keep the pencil in you shirt pocket.
The plastic Crayon Armor securely holds one of CH Hanson’s crayons and protects it from breaking since it only exposes enough crayon for marking. There’s a thumb slot for exposing more crayon and a lanyard strap.
The Crayon Armor will cost you about $4 and the Pencil Armor will run you $2 before shipping. Before paying double the product’s worth in shipping charges, check out your local Home Depot; mine carries the Pencil Armor, so maybe yours does too.
