MATERIAL: Manufactured from Aerospace quality Carbon Fibre with a high gloss finish on both sides. SUITABLE FOR: We recommend Carbon Tones Mini for both Acoustic & Electric Guitars. TONE: Carbon Fibre is hard and dense and as such has clean crisp bright tones. DESIGN DETAILS: Carbon Tones Mini are designed around the Classic 351 shape but are scaled down to a Jazz III size. We use a CNC Water Jet cutter to cut out our unique shape to exact tolerances. They are then hand polished around the edges to ensure they are perfectly smooth. CONTENTS: This Tin contains 1 of each of the Carbon Tones Mini Guitar Picks in the following thicknesses: 0. 25mm, 0. 50mm, 1. 0mm & 1. 5mm.
