The Not So Standard collection highlights the use of luxurious linen and 6-ply mat choices to further differentiate this collection of metal picture frames and treatments. It includes our “Standard” profiles in four sizes: Standard; Standard +; Standard +1; and Standard +3. The made-in-the-USA frames from Nielsen arrive as an easy-to-assemble DIY kit. The backing boards are acid-free and the glazing is clear archival framer’s grade acrylic. Purchase from the collection as designed or customize as you wish.
