Yes, it is. A sample is available to buy. However, our sample may charge double the normal price, which includes the following two parts: - Customization and testing fees - The additional fees cover the engineering costs for us to customize and test the product according to your requirements. - Sample deposit - An extra unit price is collected as a deposit. Once you place a formal bulk order after the sample order, we will deduct this deposit amount from the total fees of your bulk order. This charging method ensures that we can customize and test the product specially for your needs, and also guarantees that once you formally place the bulk order, we can start production immediately without impacting delivery time.
