Ester Book Holder from Esterbrook
A great product! I've already tried this holder out on variety of writing journals, with varying tensions and paper weight, and found it consistenly secured the pages in place. The construction of the holder is sturdier than I expected (which is a plus) and I like the "nib design." As with my prior purchases from Anderson Pens, this product was securely packaged and arrived in a prompt fashion shortly after I placed my order.
