I ship a lot - so I go through a lot of bubble mailers. This is the first time I tried this brand TruRed (never heard of them before but they were a good price). As I used them I noticed that they were overall better than some of the others I've used (Scotch Duck Brand Sealed Air etc). The adhesive strip seems better and they seem a little bit tougher (I've had some in the past that the pen poked through when writing the address on them!). These are really good ones so I'll be buying more and looking for them in a variety of sizes.
The dimensions are somewhat misleading as the construction of these mailers fuses a wide portion of the edges leaving an actual capacity much less than the stated size.
