It's a bag and my bongos fit in it.
Obviously, this bag costs less than a tenner, so you can't expect a plush padded bag...
Things to note; well, it's pretty thin - no padding at all - and its huge! I've never come across a pair of bongos that would take up all of the space in there. I think the excess size may reduce the need for padding if you crumple the bag around the drums a bit in transit (yep, it's pretty much that big). That seems to have worked for me at any rate, as my bongos have never been damaged while they've been in this bag.
Despite being thin, it's a sturdy bag - I imagine it could easily cope with loads much, much heavier than a pair of bongos.
For less than a tenner you can't really go wrong!
