I've been on the hunt for the PERFECT bookmark... and I think i've found it :) . I know that sounds a little dramatic, but stay with me for a sec. These bookmarks hook over the spine of your book and display artwork while also marking your page. I just think that's totally adorable. . I've been working on this prototype for weeks just to find the right materials and dimensions. I wanted the page marking portion to be wide enough to be sturdy, but thin enough so your pages don't tent while they're closed! I hate when that happens. - Made of polymer clay and resin, sealed with a clear varnish to make it long lasting. - Size: 5 inches from top to bottom | 1 inch wide - Since this bookmark sits over the spine, it will fit in basically any book. Please don't hesitate to reach out if you have any questions! . Read my Shop Policies for a better understanding of the shipping process.
