Yes, you can use your own small toys and trinkets in a toy crane machine, but it depends on the machine's design and your goals. For personal or home use, many modern crane machines allow customization, letting you fill them with items like mini figures, keychains, or handmade trinkets for fun events or parties. However, if you're operating a commercial machine, check local regulations and the machine's mechanism, as some may require specific toy sizes or weights to function properly. Using your own toys can add a unique touch, but ensure they are lightweight, durable, and won't jam the claw. Always test the setup to avoid issues and enhance the gaming experience!
