Open the MARELLI SAFE storeQuality without shortcuts
Construction, mechanism, interior and installation all matter. That is why we treat a safe as a complete system for everyday protection.
A steel body, locking bolts and hinges selected for the purpose of each specific model.
We verify workmanship, lock operation and set completeness before a product goes on sale.
Clear instructions, product information and direct contact with the Polish brand team.

Secure anchoring is an integral part of effective protection.
Applications
Choose the capacity, lock type and installation method to suit the location and the items you want to protect.
Documents, jewellery, cash, data carriers and items of personal value.
Contracts, laptops, keys, company cash and data that should remain under control.
Simple guest operation, emergency staff access and durable installation within furniture.

About the brand
MARELLI SAFE was founded in Poland with a simple ambition: to provide sensibly designed security products that fit easily into everyday life.
We combine e-commerce experience, technical knowledge and direct contact with users. This allows us to develop products for the real needs of homes, businesses and the hospitality industry — from compact security boxes to spacious office safes.
The right choice in 3 steps
Measure the largest item and allow extra space for future documents or equipment.
Biometrics for speed, PIN for flexibility or a key for mechanical simplicity.
Check the substrate, mounting-hole positions and door clearance after installation.
A responsible choice
For every model, we provide specific dimensions, capacity, weight, lock type, installation options and included equipment. Product documentation is prepared with European GPSR requirements in mind.
The level of protection and available features depend on the specific model and correct installation. Detailed information is available on each product page.Good to know
Brief and specific — before you choose a model.
A biometric lock is ideal when fast access matters. An electronic lock offers the convenience of a PIN, while a mechanical key lock is simple and needs no power. Choose the solution that best matches how often the safe is used and how many people need access.
Choose a discreet location that allows permanent anchoring to a solid floor or wall. Proper installation reduces the risk of the entire safe being removed and is just as important as the locking mechanism itself.
Electronic models include an emergency solution depending on the specific product: a security key and, on selected models, external USB-C power. Details are always provided on the product page and in the manual.
Not every safe meets the requirements for firearm storage. Before purchasing, check the intended use, security class and documentation of the specific model. The models shown on this page are intended primarily for documents, cash, jewellery and electronics.
