Yes. Every item is new. We do not sell returns, open-box, or refurbished goods as new.

We sell direct and skip the usual retail markup: sourcing agents, wholesalers, distributors, and storefronts. That is how the same kind of product can cost less here without cutting the materials.

Most US orders arrive in 3–8 business days: 1–2 days to process, then 2–6 days in transit. US shipping is free, and the total you see at payment is what you pay. A tracking number is emailed once your order ships.

We email a tracking number as soon as your package is scanned by the carrier. If you have not received it within 5 business days of ordering, email support@velmor-shop.com with your order number.

See our refund policy.

Email support@velmor-shop.com with your order number and a photo of the item and packaging. If we sent the wrong item or it arrived damaged, we refund it in full, shipping included.
