It's a hassle when the band keeper on a genuine CASIO G-SHOCK breaks. The band doesn't stay in place properly, making you dislike wearing the watch, and you end up putting it away in a drawer or leaving it lying around. This is a genuine CASIO G-SHOCK, Baby-G, and Pro Trek band keeper, but it also fits other bands. Silicone band keeper, loop, band holder Color: Black only Available in three sizes: 20mm width, 22mm width x 5mm thickness, and 22mm width x 7mm thickness. *Please specify your desired size when ordering.
