Finally: Small unobtrusive plastic magnets that, despite their small size, are stronger than many large magnets. The round Boston Xtra Minis can hold 12 sheets of A4 paper or one thick piece of cardboard. This makes them especially suitable for use in the office, at school or at home, where they reliably attach to magnetic boards, magnetic glass boards, whiteboards and even to magnetic paint.

The secret of their power is a strong disc magnet pressed into their plastic cap. The magnet is recessed by 0,1 mm and therefore does not touch the mounting surface. This eliminates the possibilities of surface scratches or damages to the magnetic coating. Despite their enormous adhesive force, the Boston Xtra Minis are nonetheless easy to remove thanks to their ergonomically shaped cap made of non-fading plastic.

The Boston Xtra Mini is the little brother of office magnet 'Boston Xtra' round.

Both are equally strong because they both use the same disc magnet 10 x 5 mm S-10-05-N.

The large Boston Xtra is easier to grasp, but the mini version uses less space and is priced lower.

Winner on all fronts: The Boston Xtra Mini!

The Boston Xtra Mini is not only much stronger and prettier than standard whiteboard magnets, it also lasts much longer because it is made of high-quality, light-resistant and durable ABS plastic.
The Boston Xtra Mini is so strong, you can even use it on magnetic paint.

Standard ferrite magnets are too weak for a wall with magnetic paint.
The plastic cap is manufactured in Austria exclusively for supermagnete.

The injection of the magnets is done in a sheltered workshop in Switzerland.

With a Boston Xtra Mini you receive a product that fulfils the highest quality demands.
