I got a mini one of these from my dentist and it is the best floss I have ever used and I'll be buying it from now on once I find out where I can buy it. It's a flat waxed tape. I have some very tight spaces towards the back teeth and this slides on through and simply doesn't shred or break like other ones do. It also seems to pick up more bits as well. Definitely give it a try.

Seems like a good idea for my purse but the floss is so slippery I cannot even hold it properly between my fingers and even worse, in my mouth where it gets a bit wet.
You would really think the manufacturers is selling this without having tried it themselves first!
If they did, they would know how rubbish this caredent floss is.
The Size
The floss itself! So slippery!

Normal floss packets are not that big and can easily fit in any bag really. I found these to be a waste of money, and the floss tends to break off in your mouth - maybe because they are trying to make it compact? They said it shouldn't shred in your mouth but it still did for me.

Mini packets run out quite quickly and get lost very easily.
