FAQ

Common buyer questions.

Can J&V match a product from only a photo?

Yes. A clear photo helps us identify the family, but the final confirmation is faster when you also send model, size, voltage, output, and quantity.

Do you support small sample orders?

Yes. Send the sample quantity and destination country, and we will check availability and shipment route.

Can you provide proof before payment?

We can provide real product photos, label photos, packaging references, and catalog proof when available.

What is the fastest way to request a quote?

Send model/photo, quantity, country, and key specs on WhatsApp. That is the fastest route.
