Thank you very much for viewing. Before commenting or purchasing, please be sure to read my profile and product description thoroughly to the end. I will not respond to questions that can be answered by reading the description, pointless template comments, or comments that clearly indicate the profile has not been read. Those with negative feedback in their purchase history are asked to refrain from transacting with me, so please look elsewhere from the start. Quiet and powerful 25cm ventilation fan, easy to clean, with interlock shutter. - Brand: MITSUBISHI - Model Name: EX-252LF - Size: 25cm - Design: Quiet and Powerful - Features: Easy to clean - Accessories: Interlock shutter pull - Model Code: 535 B91 I realized my mistake after installation and used it only for a few days until the correct product arrived. After that, it was returned to its original box and stored. There are no noticeable stains, but it is a used item, so please only proceed with the purchase if you understand that it is a used item and you are not concerned about minor details. Two Mitsubishi Electric genuine filter sets will also be included as a bonus. Thank you for viewing.
