A cool small bamboo makeup organizer to hold the daily/weekly mouthpieces, reeds, ligatures and other stuff drying in a handy place between sessions. This one has a drawer to store spare patches, reeds, cork grease, whatever.
Bought at a cheap decoration store called Maxi Bazar, you can probably find similar stuff in your country or on the web.
I have cardboard shoe boxes full of horns related stuff, the tens of mouthpieces, reeds, ligatures, straps, etc… we all have. But I always left the pieces currently played lying around. Voilà.
