This is a cover to prevent birds from entering the air conditioner vents. There have been reports of tragic accidents where birds have entered the vents and lost their lives. The birds I've had before didn't go on the curtain rails, but the parakeet I got last year loves being on the curtain rails, so I thought I had to do something about it, and I made this. ⭐︎Size: Approximately 42 x 107cm The first photo shows it attached to an air conditioner that is 79cm wide. * There is also a 100cm long version for smaller air conditioners. If you would like this, please let me know in the comments section. It will be 1400 yen, a 100 yen discount. ⭐︎Easy to attach and detach with Velcro, so you can wash it frequently. ⭐︎Coarse mesh that does not obstruct the air conditioner's airflow. ⭐︎White, so it's not very noticeable. ⭐︎Both sides are made with elastic, so they can stretch to fit various sizes of air conditioners (cannot be installed on extremely large or small air conditioners). Please install it to fit the shape of your air conditioner, avoiding interference with the louvers. ⭐︎Attach with Velcro to the air conditioner. If you can't stick Velcro directly to the air conditioner, such as in a rental property, first apply masking tape and then attach the Velcro on top of it, so you don't have to worry about leaving marks. ⭐︎If you are worried about using only Velcro, you can buy clear, removable hooks at 100-yen shops, and it is recommended to attach them in several places. (Not included, please purchase them yourself if needed.) ⭐︎This does not completely prevent bird accidents. Especially for mischievous and curious birds, please be careful during free-flight time. * A portion of the sales will be donated to UNICEF.
