Dust-catching filter for ventilation fans, toilets, etc. Simply stick on. Approximately 30cm. S5410 (5 sheets per pack * 5 packs) Can be used not only for toilets but also for the entire ventilation fan. Size is 30cm. - Size: 30cm - Quantity: 5 sheets per pack - Application: Ventilation fan filter ☆ I purchased these, but I no longer need them, so I am selling them. They are about 700-800 yen cheaper than the market price. I bought too many, and I have 3 sets (5 sheets per pack, 5 packs per set). Thank you. m(_ _)m
