Got mine from CountyComm. The site is down at the moment, so - no link, but my necklace image instead:
It's made of some soft rubber, which is very gentle on my sensitive skin. The spring loaded clasp has breaking strength of about 3 pounds.
On the lanyard I'm keeping:
- A led light (I forgot its name, but I call it "vampire light", because of its ability to suck out the last juice from any battery while charging);
- Recharger for vampire light is also there (wrapped with a rubber band on the left);
- 8Gb microSDHC card in a USB reader (as a flash drive, which also can work in a phone);
- Micro peanut lighter;
The AA battery is for the size reference.
