Pneumatic EnginePneumatic Engine Be a part of the once great era of steam with just a breath of air. The Pneumatic Engine is a small but fully functional example of a steam engine, except it uses air pressure instead of steam to set it in motion. Use an ordinary inflated balloon and watch the pistons and gears chug along just like the locomotive engines of yesteryear. The model comes with a built in air pressure gauge and two compartments for storage and spare parts.

BULKY & BUCKLING HANDLES
Color: Tan
The handles are bulky, and the leather buckles where you normally would hold it which is very uncomfortable. If you try to use the shoulder strap, the handles don't come off and get in the way when holding the purse against your side. Unfortunately, I first used it well past the eligible return date. I'm so disappointed. I would not recommend this product.

easy to access interior with many different pockets
Color: Desert
The back pack is awsome. It's soft, elegant and fits a lot of items...can be used in lieu of small carry on. I liked the openness of the interior area. The inside utility clear pouch was only 1 pouch, not 3 like the video. But I like it better with 1 pouch which leaves me options for larger items. The shoe pouch can be used for other items instead of shoes, if your interested.
