Our story

JCMaster Beauty is a brand of Mustbuy GmbH, which is based in Hamburg. 

For several years we have been developing and selling nail burrs for professional and semi-professional nail modeling across Europe with the JCMaster Beauty brand.

Our brands also include JSDA, which is available worldwide.


 Our objective:

  1. High quality products, which are developed on a practical basis and meet the current requirements - not always well implemented by other providers - such as longevity.
  2. Complete customer satisfaction and an outstanding overall experience: We are convinced that our customers only deserve the best and, in addition to attractive prices, should benefit from various other advantages in our shop in the long term. In view of this, our young team always tries to offer a pleasant shopping experience, transparency, excellent customer service and a constantly improved overall experience.


JCMaster Nail Design Nail Cutter Contact About Us

We have been working closely with dermatologists & beauty experts for years. As part of this, our products are developed, optimized and adapted to the individual requirements of our customers: On the one hand, we differentiate between different types of offers for private individuals and businesses and, on the other hand, the individual level of experience of our customers with nail burs.

In our shop you will find nail burs for beginners as well as advanced users. 

What others say 

The numerous reviews of our products play another key role in our constant product development. For this purpose, our team researches the opinions on the Internet and considers, for example, reviews or expert reports for further product optimization.
