      "full_description": "For those moments when a little more jingle is called for: the double-row jingle ring from Heberlein features up to 22 pairs of jingles, depending on the size, creating a lively and prominent rhythmic sound. The instrument is traditionally handcrafted in the Vogtland region of Germany.  The frame is made from ash or maple and features an integrated handle. Two rows of jingles are arranged around the wooden frame and respond directly to shaking movements and rhythmic accents. The number of jingles is matched to the respective size of the instrument.  Four versions are available: \u00d8 20 cm with 10 pairs of jingles, \u00d8 26 cm with 14 pairs, \u00d8 30 cm with 18 pairs or \u00d8 35 cm with 22 pairs of jingles. The range therefore extends from a comparatively compact jingle ring to a larger version with an especially full jingle sound.",
