Firstly, the LED acrylic USB disk works as a flash disk. It has 4G, 8G, 16G, 32G, and 64G storage. If you have a fiber laser machine, you can engrave on the alloy part making a stunning meaningful gift flash disk. It is ok to engrave on cast acrylic part with a CO2 laser machine. The edge-lit part can be crystal and it needs to be inner curved.
