K&M 15222 Clarinet Stand

The stand legs look very thin when deployed, particularly at the connection to the portion which sits inside the bell. However they are metal, not plastic, and therefore unlikely to snap. The legs fold up on a screw-in base, then slot in to the hollow bell portion, which then stores in the clarinet bell; the bell is then completely filled by the stand when in the clarinet case, so you will want to clean/dry the bell before storing.
It takes less than 15 seconds to put the stand up and down.
This is an ideal stand for orchestral/ band players as it is small enough to sit by a chair without looking obtrusive. It is very stable for this use.
If on a stage where people might bump into it, I'd probably want something with a bit more stability (but therefore bigger and not able to store in the bell!).
