We use Xit4O4 Aqua pencils as they are made entirely of plastic and rubber and without any metal parts means that they do not rust like most other click pencils. Our experience shows that they may be expensive but they really are a pencil for life. Our pencil kits come with 5 spare leads, a rubber and a stretchy lanyard for attaching the pencil to your slate. Normally sold in yellow as they show up well underwater!
