I've had exactly the same ones 2mg blisters,they are very good quality.
However i also bought some loose ones that looked absolutely identical and found them to be very weak compaired to the blistered ones?.
The blistered ones were £80 per 100 and the loose were £60 the 100,the vendor I bought them from used to have a selling thread here. I'd say if I ever bought them again I would definitely pay the extra £20 for the blistered ones that's for SURE...
Peace
Bliss.....
