I'm reaching out to discuss a potential project involving a holder designed for a pair of razors with 3-4 blades, specifically for men's shaving needs. I've previously experimented by modifying a couple of disposable knife handles, which proved to be successful. Now, I'm looking to develop a model that aligns with my requirements, and I believe your factory could be the perfect partner for this endeavor. Could you provide some insights on the costs associated with creating a prototype? Additionally, I'm curious if you have the capability to 3D print experimental units using plastic materials. Your expertise in this area would be greatly appreciated, as I'm eager to see if we can bring this concept to life effectively. Looking forward to your response!
