This Celtic engraved heddle is solid maple, it is approx 9x7" and is 1/4" thick.  Your new heddle comes with a maple shuttle so you can get started right away.  You can find band locks in another listing if you need one.   Not sure what to start with? Get the 9 short slot. With it you can make bands for 5, 7 and 9 pattern threads. To go with it, I highly recommend Susan J. Foulkes' book "Weaving Patterned Bands" for beginners. It has great information to get you started. (a wonderful customer suggested the line above :) )
