FAQ
Q1: What is the size tolerance of 2-3cm high polished black pebbles?
A1:The standard size tolerance is ±0.2cm. We use automatic precision screening equipment to classify pebbles by size, ensuring that over 95% of the products meet the 2-3cm specification. If you have stricter tolerance requirements, we can provide customized screening services, but the production cycle and cost will be adjusted accordingly.
Q2:Will the color of high polished black pebbles fade after long-term use?
A2:The black color of the product comes from the natural properties of sedimentary rock, and the surface is treated with professional polishing technology without adding artificial pigments. Under normal use conditions (indoor or outdoor non-extreme environment), the color can remain stable for a long time without obvious fading. Avoid long-term exposure to strong acid and alkali substances, which may corrode the surface and affect the color and luster.
Q3:Can I get a sample before placing a bulk order?
A3:Yes, we provide free samples for customers to test quality, size and polished effect. Customers only need to bear the corresponding express delivery fee. The sample delivery time is 1-3 working days. After confirming the sample, we will strictly follow the sample standard for bulk production to ensure that the bulk product is consistent with the sample quality.
