There may be some imperfections in appearance, so please purchase only if you are okay with that. A lazy owner made this for my own parakeet using the fabric I had. However, I wanted to use various patterns, so I am selling the ones made from leftover fabric. You can turn it inside out and wash it in the washing machine. (It is recommended to put it in a laundry net) Photos 5 and 6: Sponge is inside the floor, like in a pillow. Photo 7: For size reference (68g green cheek conure) Photo 8: A bell will be included as a bonus. Photo 9: A 10cm x 15cm board can be placed on the wall without the window. PP sheets are sold at 100-yen shops, etc. (These are not included) A side-hugging heater (please check the size) can be placed inside. Thank you for understanding that this is handmade by an amateur. (Please note that the parakeet is not included.)
