Buyer FAQ
Wholesale Crystal Blanks FAQ
The questions wholesale buyers ask before their first order - about K9 crystal blanks, engraving blanks, award blanks and ornament blanks.
What is your minimum order quantity for crystal blanks?
One piece for samples. For production orders most blanks start from 50-100 pcs per size depending on the shape - your quote will state the exact MOQ for each item.
Do you supply award blanks and trophy blanks, not just engraving blanks?
Yes - all of them come off the same K9 optical crystal line: engraving blanks, award blanks, trophy blanks and ornament blanks, cut and polished to order in any of our 100+ shapes.
Are samples available before a bulk order?
Yes. Sample blanks can be shipped worldwide so you can check weight, clarity and polish first. Sample cost is deducted from your first bulk order.
Can you engrave our logo or artwork on the blanks?
Yes. 2D laser logo engraving, 3D inner-photo engraving, sandblasting and UV printing are all done in our own workshop. You receive a digital proof for approval before production.
What is the lead time for award blanks?
Blank-only orders ship in 7-12 days depending on quantity. Engraved and custom-packaged orders take 12-20 days. Urgent schedules can be arranged - tell us your deadline.
How do you pack crystal blanks for shipping?
Pearl cotton inner packing and double-wall export cartons, drop-tested before shipment. If anything arrives damaged, send photos and broken pieces are replaced free on your next shipment.
How do I get an exact quotation?
Email [email protected] or message us on WhatsApp with your shapes, sizes and quantities. You will receive an itemized FOB quote within one business day.
