Thank you for viewing! Material: 100% Cotton Size: Width 16cm, Depth 10cm, Height 10cm Window: Round, 5cm diameter Attachment: Rings, carabiner, perch Please attach it to your cage as you like (^^) (These are not included) Stainless steel is expensive, and you may already have some at home, so please replace or attach your own. Specifications: All parts have a stiff interfacing. The bottom has sponge. ⚫︎ Important: This is handmade by an amateur. There may be some imperfections in appearance, so please only purchase if you are okay with that. A careless owner made this for my own parakeets using the fabric I had on hand. However, I wanted to use various patterns, so I am selling the ones made with leftover fabric. You can turn it inside out and wash it in the washing machine. (We recommend putting it in a laundry net) Photos 5 and 6: Sponge is inserted in 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 fit inside. Thank you for understanding that this is handmade by an amateur. (Please note that the parakeet is not included.)
