Hello. I bought a Stentor Conservatoire Outfit and in the box is a long tube that's under the bow in the case. It is a see through tube the same length as the bow and has a black bit on each end that can be taken off.
It's a string tube. You store spare strings in it (violin strings).
That's a string tube. You can put spare strings in it. In the old days when most strings were gut core, strings were sold straight, not coiled. You bought your new strings at the store then put them in a tube in your case until they were needed.
