Hello, can you tell me why you no longer sell the small S12D Case for the RD6006P? It was discontinued, but why?

[@rdtech9153]

hello, for this case, we order it in other factory, it needs hundreds of cases at a time, but in a year, it just sells 5-6 pieces, so after we sell out the stock, they do not offer us this case since we just need low quantity, sorry for that
