Metal Earth 3D Model Kits has released a photoetched stainless steel rendition of the German Type XXI U-Boat.

The German U-Boat Type XXI was a class of German diesel-electric submarines designed during the Second World War. They were the first submarines able to operate primarily submerged rather than spending most of their time as surface ships.

According to Metal Earth:

"Metal Earth is a collection of intricately designed model building kits. Each kit consists of remarkably detailed laser etching cut onto one or more four-inch square sheets of thin metal. Simply snap out the pieces, bend the tabs to attach them together and create highly-detailed replicas of vehicles and architecture that fit in the palm of your hand. Striking to look at, especially when placed to catch the light, most Metal Earth models measure about three inches long when completed. All can be assembled without any glue, although tweezers or needle nose pliers to bend the tabs will save sore fingers. Because of the tiny size of the components and the complexity of the models, Metal Earth models make ideal gifts for children ten years and older, teens, and even dads and moms!"

I have built the Metal Earth USS Arizona, and I can attest to their innovative and interesting design - but they would be challenging kits for beginners. This one is 2 sheets like the Arizona, but it is also a couple of inches longer and comes with an interior, so it may be slightly more difficult.

Since they make good gifts, these unusual little kits can be found in a surprising number of retail outlets as well as in hobby shops; I have seen them in Bed Bath & Beyond, Wal Mart, Barnes & Noble, and Target. They are inexpensive too with most priced around US$10-12.
