Mermaid Tails for swimming of Sun Tails and MJSS

Melusina and Jana sit on the village square in the MJSS World and talk about the mermaid tails of Sun Tails. The mermaid shop of MJSS offers mermaid tails in a variety of colors and designs. Jana will compete at the Mermaid Olympics with her favourite mermaid tail Aurora Borealis. Together with the pink monofin she is prepared for the tournament and can swim with her new mermaid fin against the real mermaids. On this Day the weather is perfect and the water is crystal blue and clear. Everybody in the village talk about the Mermaid Olympics. Many mermaids and neptunes from surrounding cities are expected. Melusina is very excited, because finally she is old enough to participate at the Mermaids Olympics. The program promises a lot of variety and a new spectator and participant record is expected. The Mermaids Olympics will be opened by the Mermaid Tails dving competitions. But the highlight of this year´s Olympics are the Miss Melusina elections. The girls have been preparing with their mermaid tails for swimming for months! 

For the first time in history, participants from the air folk will be there. There has never been anything like this before. The real mermaids and the air people compete against each other for the first time in swimming with mermaid tails. This was made possible by Professor Eric and Jessica from the small town of Rigbin on Earth. The daughter of Eric is Jana, Melusinas best friend. She wants a beautifula mermaid tail with bright colours. She dreams of swimming together with her best friend and real mermaid Melusina. Janas idea is to create a mermaid costume and a monofin to build a high quality mermaid tail. For years Jana have been working on and trying out different mermaid tails, but it doesn´t seem to work. Then finally the breakthrough, the brilliant idea and the solution to the hig quality mermaid tails. Their invention Eric and Jessica give the sounding name Sun Tail Mermaid. Afterwards they developed the mermaid shop where customers can buy mermaid tails and many other products of mermaids. The online shop should have the same name as the village where it all started - MJSS.World. Jana and her family were enthusiastically by the wide range of different designs and colours of the mermaid fins in the MJSS Mermaid Shop. All mermaid tails are available in high quality for adults and childrens, so the whole family immediately their new favourite swim tail. As already mentioned, Jana choose the mermaid fin Aurora Borealis. Her family like the mermaid tails Bali Blush and Blue Lagoon

Apparel, Mermaid costumes and monofins 

Melusina can still remember the day when Jana showed her bought mermaid fin with shining eyes for the first time. The new monofins named Keiki and Nunui are very popular. Professor Eric thought a lot about it and developed two differenz sizes for this reason. The monofin Keiki is designed for children and the Nunui for teenagers and adults. Jessica has designed various mermaid costumes so that Jana can feel like a mermaid. The mermaid costume is like a swimsuit and gives Jana the look of a real mermaid. With the flipper and the tight-fitting mermaid costume, Jana can quickly swim like a real mermaid with her new mermaid tail. Thanks to differenz sizes for children and adults, the different participants of the air folk can equip themselves ideally. The protective material is also very important to be able to use the mermaid costume for a long time. The high quality mermaid tail set always consists of a monofin and a mermaid costume. The monofin is available in many bright colours and can be incidually combined with the mermaid costumes. You can find the mermaid tails, mermaid costumes, monofins and a lot of more mermaid apparels in the online shop of MJSS. Furthermore the air children will find more beautiful mermaid clothing, such as bikinis, leggings and costumes for toddlers

Swimming like real mermaids - swimming aids, trick cards and more

Contrary to the real mermaids, the air childrens can only attract their mermaids from Sun Tails near the water. In the MJSS World, Professor Eric made mermaid bags to transport the mermaid tails in the best possible way. There was also plenty of room for a non-slip protective mat to attract the mermaid tail nearly on the water or for a large bath towel for the whole family. Melusina and Jana are enthusiastic about the design and the practical handling. But most of all Jana likes the developed swimming aids. The bathing caps or swim goggles not only ensure that the air children can keep up with the real mermaids, but also give them a real chance at the Olympics.

But there was another mermaid toys. Jana was even more taken with and she wanted to show it to her friend Melusina. With the toys from the MJSS World not only the air children could play, but also real mermaids in their spare time. They can swim to compete and search for the dive shell or perform various exercises with the trick cards, which not only train the swimming technique with the mermaid tails, but also are a lot of fun. So perfect for Jana to improve the handling of the mermaid tails in her free time next to the MJSS Academy. There were also other mermaid accessories for leisure time in the online shop of MJSS World.  

MJSS Academy - Learn to swim with the mermaid tail

The most of the real mermaids have never seen children from the earth. So what will the competitions between mermaids and people from the earth be like? Will the air children have a chance against the water children with their mermaid tails? Melusina was the only one of the real mermaids to swim with Jana and her mermaid tail. Admittedly, she was impressed how quickly her friend Jana learned the new swimming movement with the mermaid tail in the MJSS Academy. Once you have mastered the technique perfectly, you are really fast with her. The mermaid sport is to be preofessionalized in the futre also for children and adults, whereby the correct course material is very important. In the MJSS Academy the partners learn the correct execution with the mermaid fin and can train mermaids with the correct swimming technique in the future. So you can compete with the best at the Mermaid Olympics. 

The mermaid tails Olympics will go down in the history of the earth, Melusina is sure of that!
