I have too many similar looking or identical cases.
I used to mark the contents with sharpie script on painter's tape, but now after a few years it's all faded and unreadable.
How do you do it? First-world problem, I know.
I should make some recognition cards
I have most trouble with the Fender tweet cases.
I store mine in the case standing up in a closet and use a label maker to mark what it is on the up end of the case.
Running a Dynamo and so far no issues. I'm just using the white with black font.Is your label maker using thermal paper? Does that actually last without fading?
You guys take your guitars out the house?
Luggage tags. They have a pocket for a card, and attach to the case with a silicone lanyard.
