1/24 USAF/USN Seatbelts (Beige) : Plastic Hobby

Very easy to use. No painting needed, just remove the pre-cut belts from the backing paper, thread them though the buckles and fit them to your model.
The straps can be set to whatever length you need, just as on the real thing.
The set includes one sheet of photo etched parts with the buckles and clasps, one set of pre-cut paper straps (beige), one piece of pre-cut padding for the lab-belt (brown), and a detailed assembly guide.

Suitable for any type of US-manufactured aircraft from mid-30s to the middle of World War 2. Also these belts were sold in Navy/Army Surplus stores after WWII and were widely used in countless sports cars and race cars through the '50s, '60s and beyond.
