Yes—there isn’t a single standard “flashbulb case” you need to find; a small protective case or a simple DIY holder works well.

Two practical approaches were suggested:

1. Use a small hard case with foam. A compact plastic or rugged case can be fitted with pick-and-pluck or closed-cell foam so each bulb has its own recess. This helps prevent rattling, breakage, and mix-ups.

2. Make a lightweight tube carrier. A nylon or plastic tube sized to the bulb diameter, with end caps and foam spacers, can hold several bulbs stacked vertically. Padding between bulbs and at both ends protects them in transit. Storing them socket-to-socket can reduce movement and let them fit more efficiently.

For fragile vintage bulbs, the key is to keep them from banging together and to prevent pressure on the glass. Closed-cell foam, individual slots, or padded stacking are all good solutions.
