Query: Flimsy construction

Oxford Pocket Protectors, Grained White Vinyl, 3/packConsidering how little vinyl items cost and that it's likely these were manufactured totally by machine, and given their flimsy "quality" 3 for $10 for these is absurd. If they were like the pocket protectors of old, substantial, I wouldn't cavil. But these are incredibly flimsy. As soon as I put one into the pocket of my shirt and put a pen and a pen light in it, the outside flap began to curl up - this wouldn't have happened back in the day and is unacceptable today. Likely another "benefit" of globalization and the destruction of American manufacturing. No manufacturer name on these - likely wouldn't be so if made in the USA with the quality we used to have. Buy them if you wish - I'll never buy them again.
