About us

Martyna Konowrocka

Martyna Konowrocka, at the age of only 22, created and runs the Mart's Bags company. This business is the leader in production of ecological cotton bags in Europe. Currently, the company produces one million cotton bags annually

Initially, the company has been on the Polish market, but in a relatively short time the activity gained its fans and customers in other countries of the old continent.

Martyna's vision of the company is based on ecological production of goods and supporting and promoting Polish business.

The businesswoman grew up in an enterprising home. She graduated from the Warsaw School of Economics and started her business in 2007 after a short attempt of full-time work. She created her own vision of a cotton bag, focusing on the highest quality of workmanship and the possibility of full personalization of the product. All her products are made in Poland from natural materials.

In private life, Martyna is a full-time mother - she brings up two children with her husband, runs a large house and enjoys spending time with her family. She is also a travel lover, and in her free time she trains fitness. 

Promoting value is an integral part of the daily functioning of Mart's Bags and communication with the client. Cotton products support other brands and inspire at the same time. Concern for the environment and Eco productions are currently in vogue, and Martyna, as one of the pioneers, started this trend in marketing 13 years ago.
