This bag comes as a package deal with the Korg SP-250 but it is waaaaay too big!!! Ridiculous, I'm really really frustrated about this and would rather have spend a little more money on a bag that fits better. I recommend that Thomann no longer offers this product combined with the SP250: very very annoying / frustrating.
If you have a keyboard that's about 1,4x the size of a normal stagepiano, this is a nice bag though.
