For Gadget, IT, technology or accessories products, there are always new products from time to time. This causes us to not be able to immediately install these products directly due to limited time for quality checks, receiving orders, packing, and answering questions, etc., even though there are so many other products that we haven't had time to install on this shopee. . For this reason, we are very happy if our customers, both resellers, dealers and end users, can provide input regarding requests for any gadget/computer/IT accessories products, whether: anti-scratch, case, battery, casing, USB cable, OTG, card reader, speaker, sim cutter, etc.
