I purchased this new, but the size didn't fit, so I stored it without ever using it. I am not considering lowering the price. The following is quoted from the sales site where I purchased it: [Charm with a bird inside] Perfect for messages so you don't startle others when traveling on trains, etc.! No more embarrassment with the cockatiel's whistling! [Heat and Cold Retention] Perfect for both cold winters and hot summers with the included cold storage bag. The simple design makes it easy to remove! (Can be secured with tape-attached Velcro.) Use it only when needed, and clean it by wiping it. You can replace it immediately if it gets dirty. * When cooling, please use in conjunction with a hot water bottle or frozen plastic bottle. [Specifications] Top: 53cm wide Height: 35cm Bottom: 28cm long x 30cm wide Gusset width: 28cm [Lid that also serves as a core material bottom sheet] It can be a lid for large carry cases such as Heartful Carry, and the birds can feel secure. For small carry cases or plastic cases, Place it on the bottom for perfect stability. Lid: 27.5cm long x 28cm wide (core part) + 10cm #bird #parakeet #carry #carry bag
