Advice - carry water bottle and side stand plate?

[Wisedrum]

Looking for some suggestions on simple ways to carry a couple of things with me on my daily rides, a water bottle and a small flat alum plate I place under side stand when stopped in asphalt parking lots, without resorting to a tank bag or strapping a bag on somewhere.

Have the factory luggage rack installed and a chic Design road comet fairing, like the clean lines of the bike and unless I'm going off for a while would prefer not to add bags.

Any clever solutions or suggestions?

To me it's a thermo can filled with green tea flavored with moroccan mint, milk and some honey instead of your water bottle.
I carry it together with a book or two and your mentioned small flat alum plate, in my case made of plastic, not often used,
but you'll never know, where your bike has to be parked, in the saddlebags of the CB. Often I add a few fabric bags, if I stop at a
supermarket, to buy me some necessary things.
Mostly that's all. But it can differ.
