Shimomura Kihan Ventilation Fan Filter Replacement, 5 Sheets [Made in Japan] 35x35cm 22135

Shimomura Kihan Range Hood Filter Replacement, Set of 5 [Made in Japan] Prevents Oil Stains, Easy to Install, Just Cover, Flame Retardant, Covers Range Hood Sides, 35x35cm, Extra Purchase, Add-on, Disposable, Range Hood Cover, Kitchen, 22135

When I replaced the range hood at my parents' house with a new one, I bought these to prevent stains, but I couldn't install them.
I tried to install one sheet, but since I tried it on the new range hood, it's not very dirty.
Please understand this before purchasing.
I hope someone can make good use of them.

For shipping, I will put them in a bag and compress them to a thickness of 3 cm.
