What is an Engravable Signature Frame? An Engravable Signature Frame is an elegantly polished silver alloy (not cardboard) mat that your friends and family engrave their names and well wishes into. This technique is done by using our specially designed engraving scribe which writes much like a regular ink pen. Once fully signed, the mat is finished and a photo can be inserted in the center thus creating a unique keepsake. Signature Frames are the NEWEST guest book for any special occasion. Use an Engravable Signature Frame for such occasions as weddings, bridal showers, baby showers, retirement parties, graduations, anniversary parties, corporate celebrations and much more! We supply to the bridal industry, gift industry, engraving, framing, and special event industries.
