This design is an EB mug shape bookband, which is available with the option to be personalised with a label on the front - or plain if you prefer.  They are slightly padded (a little less than the hanging decorations, so's not too be too thick inside your book) with a colour co-ordinated elastic band approx 6mm wide & 32cm long, to hopefully accommodate a range of book sizes & thicknesses!
 
The mug measures approx 9cm high, and 10cm wide, to the handle, and can come plain, or with a label and name in gold lettering. 
These bookmarks are made with genuine Emma Bridgewater prints, and are made up of 2 layers of fine padded felt.

All my decorations are handmade to order in my Sussex studio.
