Pendant is 1 x 1.5 inches (2.5 x 4 cm).
Ball chain is 24 inches (61 cm), slips over head without undoing clasp.
Lead-free solder.

Let me know if you'd like this on a keyring instead of a neck chain.

I try to show the colors as accurately as possible, but please keep in mind that colors will vary slightly from monitor to monitor.
