I am looking for lighting bricks that are compatible with LEGO bricks. I would like to order between 700 and 1000 pieces in various types. The desired delivery time is 1 week, with the delivery address in Shenzhen, China. If the quality is good, I plan to place regular long-term orders. The most important requirement is that these products must have a valid European CE (Conformité Européenne) certificate. The CE certificate is similar to the CCC certificate but specifically for the European market. See example in the pictures
