It seems these were given to passengers in first or business class on KLM Royal Dutch Airlines, but it's unknown if they are still offered. They are Delftware houses. The shape of the houses is wonderful, and the blue roofs and windows are impressive. There are many collectors of these items. The chimneys are sealed, but originally they were filled with Bols Dutch gin. One of these items appears to have almost completely evaporated, while the other still has some remaining. There are no signs of the seal being broken. They seem to be old enough for the gin to have vaporized. They may be considered antiques. The shorter house is approximately 9.5cm tall, 5cm wide, and 5.5cm deep. The taller one is approximately 11.5cm tall, a little over 4cm wide, and about 4.5cm deep. These are not new and are quite old. While there are no noticeable scratches or damage, please refrain from purchasing if you are looking for a perfect item or are overly concerned with condition. Due to the nature of the product, we cannot accept claims or returns after the purchase is complete. Thank you for your understanding.
