Small change putting that ends in short life(Buy it in 100 yen shop)

From the theme of "Track back fellow" this week

I was using the small change putting that had been bought in 100 yen shop before about the failing shopping. But, the fastener will break in several months, and it has become no use. When the cheap one is bought, is the ability to ascertain whether it can be used forever necessary and indispensable?
