As an adult, I find it a little irritating that my niece, who is taking keyboard lessons, always carries her keyboard around in her arms. After seeing this bag large enough to fit an 88-key keyboard, I knew it was the perfect gift for her.You should be able to fit a regular 88-key keyboard into this bag, but it's a good idea to measure first. It can be used both vertically and horizontally thanks to its wheels and sturdy nylon handle. The shoulder straps are ergonomically designed to relieve strain, and their length is adjustable to suit users of varying statures.To prevent damage to the keyboard during transport, this bag is constructed from tough Oxford material and lined with thick foam. This bag protects the instrument from dirt and dampness.There are three inside Velcro straps that may be adjusted to keep your keyboard from moving around while you're on the go. Extra materials and accessories can be stored in the three zippered exterior pockets. This is a must-have for any keyboard owner.
