Phil-tan Range Hood Cover for Shallow Type (5 pieces)

I purchased this as a ventilation fan cover from Amazon.
Unfortunately, the size did not fit my home's ventilation fan...

It is new and unused.

I opened it to check if it would fit.
Please refer to the photos for details.

Size
46.5cm (Height) x 33cm (Width) x 5cm (Depth)

Thank you.
