Usage measurement
No cookies
We count visits and see which pages, products and searches visitors use. On checkout we also measure completed steps, selected options, broad error categories and active time; we never store what you type. There are no cookies, nothing is stored on your device, no profile is created, and your IP address is never kept. Because nothing is read from or written to your device, this needs no consent. If you would still rather not be counted, you can stop it here. Details are in the Privacy Policy.
Your visits are not counted. This is saved in this browser only.

The Sundia string feels slippery at first and slowly gains friction after use. The Henrys and PlayJuggling strings feel grippy and rigid.
How long should I cut my string?
Measure it against your body. With the diabolo on the ground, the string should reach from the ground to between your collarbone and your chin, roughly 1.5 m for an adult. Low multi-diabolo play wants more: about ground to nose with four diabolos (4low), and above the head with five (5low).
How many strings are in a roll?
A 35 m roll makes about 23 strings, and the 525 m box about 350.
How often should I change my string?
When it goes fuzzy, stiff or too grippy. Every one to three weeks if you play daily, every few months if you play now and then.
My new string feels too slippery. Is it faulty?
No, that is normal for a fresh Sundia string. It settles after one or two sessions, so play it in before judging it. Running it over your skin makes it more slippery for a while, and running it under a shoe sole makes it grippier.
1.3 mm or 1.5 mm string?
1.3 mm is the standard and what we recommend. 1.5 mm has more friction and gives more direct control, which suits a fixed axle.
White or coloured string?
It is the same string. White is the default, what most players use and the easiest to see on video.
