We are looking to open a headshop in Switzerland that focuses on sustainability and eco-friendly products. For this purpose, we require grinders, ideally in two different designs. One of them should be made of two-layered plastic, simply designed with the inscription "4zaza" in black and pink, with both inscriptions in white. For the other grinder, a four-layered design is preferred, using high-quality materials to prevent the ground material from sticking. We will provide you with the desired design. Additionally, we would like to have the design applied to rolling trays. If you have any further ideas for design or suggestions for other items that sell well, we are open to them. Furthermore, we need packaging for these products. The certificate requirements should comply with Swiss standards, including a conformity declaration, CE marking, and quality assurance. Can you assist us with this? Thank you very much!
