The worst I've seen in the construction of a plastic object in general... The edges have excess plastic that probably "overflowed" from the mold and the cap doesn't fit. Wasted money!

It's a shame I didn't find a Greek equivalent!
This one, however, is of mediocre quality, it had flashes (defects) everywhere because the injection mold needs repair or reconstruction. Most importantly, the threading doesn't screw in properly, it "skids", resulting in it wearing out and breaking after the first few times. I like that I bought 3 to give to acquaintances, hahaha.

This is what the deindustrialization of our country has led to!!!
Not even a mold for gas caps.
