Set of 4 plastic easy chuck closures. Mail-bin is not supported. Please use it to adjust the free shipping costs for delivery by courier. Each item is individually packaged in a PE bag, but there are no labels or instructions attached. Simple but subtle curves as shown in the pictures, ensuring that the zipper is closed with light force. In addition, since it is very nostalgic, it can be used in large bags such as 11.0 lbs (5 kg) and 6.6 lbs (3 kg) items. There is also a hole for the string to pass through.
