Created from LP's newest plastic formulation, Bellastic Plastic, these blocks add both musical and visual color. Their sounds are sharp and cutting with explosive punch. Use these blocks in place of wood blocks, rim shots, or whenever a loud blast is needed. LP Blast Blocks are available in two vibrant pitches and colors: high pitch, yellow and low pitch, green. Each block is fitted with LP's forged eye-bolt assembly for secure placement on any 3/8" diameter rod.
