Description

Sundia string uses a mix of nylon, polyester and cotton. As a result, the double weave string is stronger and resists breaking. It feels smooth from the start, and the flexible string creates clean slacks and whips.

The 1.3 mm string has low friction with the axle, which allows longer spinning time and gives more freedom. A widely used string, recommended for all levels.

Good string!
Breaks in quickly. Feels a little stiffer than the white Sundia string.

Ready to Use, Durable and Versatile
A great all-round string for both practice and performance. It offers excellent durability and a slight degree of elasticity. Unlike traditional Henrys string, it’s ready to use straight out of the package, with no break-in period needed, making it perfect for both training and stage use right from the start. Keep in mind that it will gradually stretch and lose some of its elasticity over time.

Black vs backgrounds
This string performs exactly like its counterparts in other colors. Keep in mind that it requires specific stage lighting to remain visible, especially against dark backgrounds or a black curtain. However, this can be an advantage when creating invisible-string effects or magic illusions, and it may work particularly well on stages or in environments with very light or white backgrounds.

FAQ (7)

What are the different types of string?

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.
