Breathable transparent acrylic pipe, transparent cap, mesh water filter,

Thank you for looking.
This is a transparent mesh pipe.
I attach it to the tip of the overflow tank's corner cover water supply pipe.
I keep fish to process leftover food in the corner cover,
and I use this product to prevent the water supply from falling.
It has never fallen off, and the holes are large enough that debris does not accumulate.
It can also be attached to the drain to prevent the sound of falling water.
I think it's a rare product, so how about one?

New and unused. This is the price for one item.
Inner diameter is φ50mm.
