If you are willing to pay for it, you should get some kendama eye candy. I am talking about the Sweets Chameleon. It is a bit pricey, but it really looks good. It also has an Aisuru finish on the ball, which makes it nearly impossible to chip. It was even tested by being thrown down like 40 ft of stairs, and the only damage done was a a few dents, but no chips. Of course this kendama is not needed, but if you want to go to cheap any KendamaUSA will work for you, like lets say the Classic which a lot of people in the Kendama Community prefer over most of the KendamaUSA line of kendamas (personally I like KendamaUSA and there all their products, but some people hate on the way the kendama is built as a whole piece, not two pieces like the others). However in reality any kendama will do the job as long as it isn’t a knock-off, but since your buying from here you don’t have to worry about that.
One final recommendation that a lot of beginners like is the Sweets Atack, which has a grippy surface on the ball, and gets even more grip the more you play with it. People like this kendama because it makes certain tricks easier to land, hence why beginners like it. Although as you get more advanced you may want to learn more on something less sticky, in order to challenge your skills. However that is a personal choice and not something you have to do.
So to recap (I know this got a bit wordy) Sweets Chameleon, if you want something flashy, Kendama USA Classic or Tribute is you want something cheaper, but is still perfectly fine to play with, or finally a Sweets Atack, if you want something that will make things easier for you as you first begin. Good luck with your choice, I’m sure you’ll enjoy whatever you choose.
