Tesco Dental floss comes in a pack of 2. Each floss dispenser is a plastic blue triangle and about 2 inches by 2 inches, with a flip top lid. Inside the lid is where you pull the floss from and there is a small metal cutter to allow you to break the floss at the length of your choice.
The floss itself is a thin strip about 1mm wide. It has a minty waxy coating and it does glide quite easily through your teeth. You need to break off enough to allow yourself to wrap it securely around a finger on both hands, to ensure you get a good grip on it or it may get stuck between your teeth - although this isn't a major problem as you just use another piece of floss to get it out.
The floss leaves a pleasant minty taste on your gums and is - in my opinion - very effective. I've certainly never had any problems with my gums and my dentist says they are in great condition.
This floss does have a tendency to fray if you are not careful, so you have to make sure you use a different piece of the strip between each tooth.
Even with daily use this pack will last you a long time - probably 5 or 6 months.
Having 2 in a pack is very handy as you can keep one in your house and one in your bag/car/desk for emergencies!
For price it's hard to beat. Each triangle contains 50 metres of floss, so that's 100m for £1.20. The equivalent branded products are around £2.50 for 25 metres and I don't see how they could be that much better.
This is a decent product at a very reasonable price
