Made with 12mm cedar wood. Width 90cm, depth 140cm, height 230cm. Weight 500g. Hole diameter 32mm. Comes with a durable rubber cord. The rubber cords (4) will be attached when shipped. They are attached by tying them to the wood (Photo 1). This is a handmade item, unlike mass-produced products. Since natural wood is used, there may be knots, scratches, warping, unevenness, or color variations. We ask for purchases from those who understand handmade items. We do not accept returns or exchanges except for damage or malfunction upon delivery. This birdhouse is intended for small wild birds (sparrows, great tits, marsh tits, coal tits, etc.). Wild birds will use old nesting materials as they are or renovate them if they like them. It seems they feel more secure with old nesting materials. There is no need for humans to clean the nest; they will remove anything they find bothersome themselves, and they will adjust the height themselves to make it easier to raise their young. Please be aware that if humans peek while they are incubating, they may abandon their young. It is better to peek after the chicks have hatched. There are many natural enemies. If possible, it is ideal to install it facing north, in a place with many trees and branches, at a height of 3 meters or more.
