Again this is a problem with molding plastic items. Where the mold comes apart there is often a slight "flashing" of the plastic. This is caused by molten plastic seeping between the mold halves. Paying for a worker to trim all this flashing would be cost prohibitive. However, it is usually a simple matter to trim it yourself using a razor blade or a very sharp knife.

What do you expect...WalMart is an example of the "Race to the Bottom".

By competing on price (Walmart's reason for existence) they are forced to increasingly cut corners on the quality of raw materials, labor, and workmanship. Or else someone else will make the same product for less cost.

A Race to the Bottom.

The results: yes indeed - less expensive items on the shelves. Just what the common herd clamors for. But the real price you pay is often shoddy stuff that can let you down at the most inopportune times.

Imagine needing your water in a survival situation, only to find that great container you bought so cheaply has leaked it all away. Sounds like you paid a little for something that did not work when you could have paid a medium amount for something that isn't likely to let you down.

I know for a fact that many manufacturers make two sets of the same items - the first set of of less quality they make for WalMart stores and another, seemingly identical but better quality set they sell to other stores that are not so price conscious.
