Frequently Asked Questions (FAQ)
-
What is the minimum order quantity (MOQ) for custom size rings?
For standard sizes we have no MOQ – you can order just 10 pieces as samples. For custom sizes, the MOQ is typically 100-500 pieces, depending on the complexity. We are flexible and can discuss based on your project. -
Can you engrave logos or text on the ring surface?
Yes. We offer laser engraving for logos, serial numbers, or custom text. The engraving is permanent and does not affect the brushed finish. -
What is the tolerance on the inner and outer diameter?
Our standard tolerance is ±0.1mm. For precision applications, we can achieve ±0.05mm with additional cost. Please specify your tolerance requirements when placing an order. -
Do you provide free samples?
Yes, we provide free samples for existing stock sizes (OD 20mm x ID 17mm and other common sizes). You only need to pay the shipping cost. Custom samples incur a small tooling fee, refundable upon bulk order. -
Are these rings suitable for people with sensitive skin?
304 stainless steel is hypoallergenic (nickel content is low, but not nickel-free). For those with severe nickel allergies, we recommend 316L stainless steel option, which is also available upon request. -
What packaging options do you offer?
We can pack rings in bulk poly bags, individual heat-sealed bags, black velvet pouches, or custom cardboard tags. We also support white-label packaging with your brand. -
