Kleve indeed :D

why? dunno hahah cause the hole is round but why ?

Because a round cover can't fall in, no matter what angle and orientation. A square one can. Great engineering thinking, that, I like it.

Try it with some round and square Tupperware-like stuff if you don't believe me.

Usually when you see a square cover it has hinges to attach it, round covers don't need that.

oh, you're right! ^ ^

Duh.

Heehee. You tried it?
