In 2014, NORWIK introduced a new weighted ball named the Viking Norwik, which is offered in 75mm and 5 different weights:
- 134 grams
- 201 grams
- 268 grams
- 335 grams
- 402 grams
The standard size is by far the most popular model. NORWIKs are offered in 5 vibrant colors (yellow, orange, red, green, and blue) as well as white.
The NORWIK juggling balls have gained popularity since their release in late 2011, and are used by a number of jugglers worldwide. The NORWIK balls' biggest market is currently Scandinavia and northern Europe.
The NORWIK website lists several advantages of using NORWIK balls:
- They are big enough to be visible on stage, and small enough to easily hold and release four with one hand.
- They don't stick to each other or to your hands.
- The sand makes them much easier to throw cleanly than other balls, including other Russians.
- They are very light, so you can make high throws more easily and juggle longer without getting tired.
- The don't wobble in the air like other Russian balls sometimes do.
- They have more air resistance than smaller balls, so they move a little more slowly in the air.
- They are very easy to catch due to all the sand going to the bottom of the ball.
- They are very good for balancing, pinball style juggling, and BBB.
- They have a very dead drop compared to other Russian style balls that are filled more.
- A tiny air hole in the ball helps it keep its size and roundness better than other Russians.
