By Jan Ruzinsky, a custom Green Tuscany shell cordovan leather strap (22/16, 120/90) for my Edifice Bluetooth EQB-1000.
And another ...Casio, this time a very cheap one, the sapphire Edifice plain date quartz.
That one will wear Jan's older straps that I have used very little, a burgundy Horween shell cordovan and a suede beige. These are 20/16, 115/75mm.
I find Jan's straps to be of excellent quality and of great value. He's based in Slovakia, so no customs charges for his products.
The green above cost me €65 incl. p&p.
