Constructed of kiln dried, environmentally friendly Siam Oak, the Puerto Rican Flag Mini-Bongos feature 3-1/2" and 4-1/8" calf-skin heads, chrome-plated hardware, miniature Comfort Curve II rims, and rubber tips to prevent them from marring any surface. 4"-tall bongos are fully tunable and produce quality tones. Hand-painted Puerto Rican flag finish.
