Inquiry about Book Safe with Combination Lock NEW

We are interested in purchasing book safes with combination locks for a corporate gift project. Required specifications: - 3-digit combination lock; can the end user set their own code, and can you preset a unique code for each unit before shipping? - Must appear as a realistic book on a shelf. - Approximate dimensions: 24 x 16 x 5.5 cm; please advise on weight per unit and material (steel construction with printed paper cover; confirm if real paper pages are used). - Cover options to be quoted separately: Option A – stock designs: share images of all available designs, emphasizing plain dark colors like black, navy, and dark green. Option B – one custom design for the entire order: we supply a print file for the front and spine, and all units receive the same cover. Initial order quantity: 100 pieces, with the possibility of larger follow-up orders. Please provide pricing for both cover options along with lead times.
