The Picture You Always(Pat. Pend.) photo holder uses a pin clamp attachment to the vase–simple in design, low cost and effective. Can be used in any climate conditions, is fully assembled and requires no tools for installation. The photo holder is not affected by moisture and includes a clear sleeve to protect the photograph, though photos should be laminated before insertion to make them waterproof. Most printing services or OfficeDepot / OfficeMax can do this for a small fee.
The price is $19.95 USD for a pair of photo holders with vase clamps, one for portrait (vertical) photos and one for landscape (horizontal). Shipping to the U.S. (50 states) is included.
