All items are made to order and there's typically a 4-5 week leadtime.
One empty case, including buttons (select color) and screw. This case fits the second generation controllers with slide off bottom. Will not work on original prototype/beta controllers. There's a separate ordering process for those. Please ask.
Case can either be ordered in the original "ABS" like material, which has finer/smooth detail, or the new Nylon material that's stronger and less likely to break, but might have slighly softer detail. It's also available in Alumide which is made from a polyamide powder and fine aluminum particles. Slightly rough surface and may become dirtier quicker than standard Nylon case, but can be washed.
Best option is either Nylon or Alumide, but parts should be interchangeable. If Case Type option does not show then it means they're out of stock.
