Rainer Lab · Slovenia
Small enough to listen. Experienced enough to deliver.

Manufacturing with a brand owner’s perspective.

Rainer Lab is the private label division of Rainer d.o.o., the company behind Slovenian cosmetics brand 4kidsandus. Since 2014, we have developed and manufactured cosmetic products in our own production.

Because we also build our own brand, we understand that a successful product is more than a formula. It must work commercially, communicate clearly and be realistic to manufacture.

Before we begin.

What is your minimum order quantity?

Minimum quantities start from 500 units per product for selected formulations and standard packaging. The exact MOQ depends on the formula, fill volume, packaging and level of customisation.

Can you develop a custom formula?

Yes. We can work from a suitable existing base or develop a custom formula around your product brief. Development scope, testing and documentation are quoted separately.

Do you work with international clients?

Yes. We welcome enquiries from brands, distributors and retailers across Europe and international markets. Products are manufactured in Slovenia, European Union.

What should I include in my enquiry?

Tell us the product category, target market, desired quantity, packaging preference, target price and expected launch date. If some details are not yet decided, a short concept is enough to start.
