RZ400V2-WHの高価買取価格

It looks like you provided a code that could be a barcode or a product SKU (Stock Keeping Unit) followed by a model or product name. However, I don't have access to product databases to look up specific items using barcodes or SKUs.
The code "6940526113652" appears to be an EAN (European Article Number), and "RZ400V2-WH" looks like a model number for a product, possibly an electronic item, accessory, or apparel.
If you need specific information about this product, you might want to check online retail websites or databases that track EAN/UPC codes, or provide some more context regarding what type of product you are inquiring about.
