Minimalist here is not an aesthetic. It means you can point at each object and say what it is made of, what it is for, and how it is washed.
Give every object one job
A lubricant has a job. A condom has a job. A toy has a job. If something in the drawer is a gift you never identified, it does not earn a place beside the things you understand.
Write the material on a note if the original box is gone. If you cannot, the honest status is unknown, and unknown is a reason to stop using it on sensitive skin.
Match the set so the labels agree
Put the condom material, the lubricant, and any toy material in one sentence. If you cannot confirm they are compatible from the labels, do not combine them because a video did.
Water-based lubricants are often the simpler match, but 'often' is not a label. Read the one in your hand.
Retire by function, not by guilt
You do not need a backup in every colour. Keep the object you can turn off quickly and clean. Pass nothing on to another person as a surprise.
When you are ready to replace an unknown object, use the Sexual index to look for disclosed materials. Bare will not name a winner.
A small kit is not a safety certificate. Clean what you keep, and stop if skin or tissue complains.
Continue with what natural feeling claims or the safety and consent notes.
