The fine bristles are made from durable polypropylene, combining excellent resistance with a soft construction that is also suitable for sensitive playing surfaces. Two adjustable rubber rings allow the spread of the polymer fibres to be modified as required. With the fibres spread wide, the brush can produce both full bass tones and high slap sounds. When bundled more tightly into a rounded rod shape, playing techniques similar to conventional wooden sticks or rods become possible. The rubber-covered grip provides secure and comfortable handling. With a length of 365 mm and a diameter of 22 mm, the Poly Brush is a versatile percussion tool for a wide range of playing techniques and sound options.", "additional_text": "Model: Poly Brush \n Instrument type: Percussion brush \n Bristle material: PP polypropylene \n Fine, soft polymer fibres \n Grip: Rubber \n Weight: Medium \n Two adjustable rubber rings \n Adjustable bristle spread \n Suitable for bass and slap sounds \n Also suitable for stick- and rod-like playing techniques \n Suitable for sensitive playing surfaces \n Suitable for drum kit and cajon \n Length: 365 mm \n Diameter: 22 mm \n Manufacturer: Rohema Percussion OHG", "sku": "61295", "mpn": "61295", "ean13": "", "upc": "", "brand": { "@type": "Brand", "name": "Rohema Percussion OHG", "url": "https:\/\/musiccraft-instruments.com\/en\/rohema-percussion-ohg_11" }, "manufacturer": { "@type": "Organization", "id_manufacturer": 11, "name": "Rohema Percussion OHG", "url": "https:\/\/musiccraft-instruments.com\/en\/rohema-percussion-ohg_11" }, "supplier": { "@type": "Organization", "id_supplier": 1, "name": "Migma e.G." }, "main_category": { "id_category": 89, "name": "Brushes", "link_rewrite": "brushes", "urls": { "agent": "https:\/\/musiccraft-instruments.com\/en\/mcc\/mcc_agent\/category?id_category=89&setCountry=0&setCurrency=1", "human": "https:\/\/musiccraft-instruments.com\/en\/brushes-89" } }, "categories": [ { "id_category": 4, "name": "Instruments", "link_rewrite": "instruments", "urls": { "agent": "https:\/\/musiccraft-instruments.com\/en\/mcc\/mcc_agent\/category?id_category=4&setCountry=0&setCurrency=1", "human": "https:\/\/musiccraft-instruments.com\/en\/instruments-4" } }, { "id_category": 6, "name": "Equipment & Essentials", "link_rewrite": "equipment-essentials", "urls": { "agent": "https:\/\/musiccraft-instruments.com\/en\/mcc\/mcc_agent\/category?id_category=6&setCountry=0&setCurrency=1", "human": "https:\/\/musiccraft-instruments.com\/en\/equipment-essentials-6" } }, { "id_category": 7, "name": "Restoration", "link_rewrite": "restoration", "urls": { "agent": "https:\/\/musiccraft-instruments.com\/en\/mcc\/mcc_agent\/category?id_category=7&setCountry=0&setCurrency=1", "human": "https:\/\/musiccraft-instruments.com\/en\/restoration-7" } }, { "id_category": 5, "name": "Highlight", "link_rewrite": "highlight", "urls": { "agent": "https:\/\/musiccraft-instruments.com\/en\/mcc\/mcc_agent\/category?id_category=5&setCountry=0&setCurrency=1", "human": "https:\/\/musiccraft-instruments.com\/en\/highlight-5" } } ], "features": [ { "id_feature": 1, "id_feature_value": 3, "name": "Product declaration", "value": "Single item" }, { "id_feature": 15, "id_feature_value": 130, "name": "Taxation", "value": "Standard Rate" }, { "id_feature": 9, "id_feature_value": 210, "name": "Instrument", "value": "Drums" }, { "id_feature": 9, "id_feature_value": 451, "name": "Instrument", "value": "Cajon" }, { "id_feature": 9, "id_feature_value": 446, "name": "Instrument", "value": "Brushes" }, { "id_feature": 22, "id_feature_value": 172, "name": "Intended Use", "value": "Intermediate" }, { "id_feature": 22, "id_feature_value": 171, "name": "Intended Use", "value": "Beginner" }, { "id_feature": 18, "id_feature_value": 445, "name": "Core material", "value": "Polymer fiber" }, { "id_feature": 18, "id_feature_value": 375, "name": "Core material", "value": "Rubber" } ], "agent_faqs": [ ], "images": [ { "id_image": 2986, "cover": true, "position": 1, "legend": "Rohema Poly Brush \u2013 Versatile Percussion Brush with Polymer Fibres", "url": "https:\/\/cdn1.musiccraft-instruments.com\/2986-large_default\/rohema-poly-brush-percussion.webp" } ], "shipping_weight": { "@type": "QuantitativeValue", "value": 0.5, "unitCode": "KGM", "note": "Shipping weight, not product content." }, "variant_model": { "has_variants": false, "variant_count": 0, "default_id_product_attribute": 0 }, "offers": { "@type": "Offer", "offer_scope": "product", "id_product": 509, "id_product_attribute": 0, "url": "https:\/\/musiccraft-instruments.com\/en\/p\/rohema-poly-brush-percussion-509.html", "price": 24.90, "priceCurrency": "EUR", "availability": "https://schema.org/InStock", "itemCondition": "https://schema.org/NewCondition", "seller": { "@type": "Organization", "name": "musiccraft -
