Do not do business with there guys! They do not deliver the agreed quality or keep the promised shipping date. We had a sample order from them with good quality, but this is just a cover. The next bigger order was rubbish quality and late for 2 months. The production was promised 8 week, but was 16 weeks in real life. After receiving bad quality we sent back 790pcs unusable tweezers. This was 4 moths ago and we still have not received the fixed tweezers despite the many promises from Billu Brothers Surgical.
