The BAM Bow postal tube, as supplied with BAM trekking cases, is a strong plastic tube for safely transporting, storing or posting bows. The tube has two strong screw-on end caps. The BAM Bow Tube with Carry Strap is suitable for violin, viola and cello bows. It does not have any internal padding, therefore an internal BAM Bow Sleeve Velvet is recommended.

The tube dimensions are 79 cm x 5 cm. It comes with a shoulder strap to carry one bow. It can be used alone or with the Trekking or Overhead Hightech case.

The BAM Cabin (Overhead) violin case comes with two elastic retainer straps for attaching this tube to it when not being used in the aircraft cabin.
