Most suppliers in the glass and glassware sector offer verified work emails, phone numbers, and business documents to build trust with buyers. Charming Crystal Co., Ltd. does not have any of these verifications — which raises red flags about their legitimacy and ability to handle large or long-term orders. While their key products like pearl and glass drinkware are in demand in Vietnam, the lack of verification makes it risky to engage without additional due diligence. Buyers should request proof of identity, such as a business license or bank statement, before placing any orders. Without verified contact details, communication may be slow or unreliable. The absence of annual turnover data also makes it hard to assess their business scale or financial stability. This profile suggests a higher risk compared to typical verified suppliers in the same industry.
