I purchased this new and used it for only a few hours after opening. Set Contents & Details: * Dedicated clear plastic case Young birds require temperature management, so a typical "birdcage" is still too early. Let's raise them in a plastic case that is easy to manage the temperature. ※ This case can be used for moving even when they become adults. Size: Approximately 300 x 195 x 205mm * Bird mat Broadleaf tree chips with few allergens and irritants. Highly absorbent and cushioning, making it ideal as a mat for young birds. * Chick feeding set A specially shaped spoon supports feeding chicks. An essential feeding set for raising chicks. * T-shaped low perch Once the chicks are growing well, practice "perching" inside the case! It's a low perch, so it's easy to perch on! Can be used even as they grow. If you need it, please consider purchasing it.
