Double Panel Clear Acrylic Floating Frame with Silver Hardware for Art & Photos (9 in x 12 in) Size:9 in x 12 in   Double panel frames offer more protection for the artwork as the artwork is sandwiched in between two panels. A second piece of acrylic, as opposed to magnets, is used to keep the artwork secure in the double panel frames. We recommend a bit of archival photo-safe adhesive on the back of your art/photos/EPs etc for the double-panel frames. To change out double panel frames, unscrew the frame from the wall and separate the two panels. Replace existing artwork with new artwork and screw the panels back in to the wall. This process should only take a couple of minutes. Either panel can be on top. However we recommend putting the thinner panel in the back. Float your artwork and posters off the wall while fully enclosing your art in between two panels of acrylic. Ideal for all images. HOD acrylic is mar-resistant and flame polished giving your frame the perfect finishing touch. When you want to change out your display, just unscrew the caps on the hardware and lift off the acrylic.About Our Service:Prompt and Good Service.Reply the inquiry within 24 hours.Ship products on time.Try the best to solve customers' problems.Check carefully before parcel shipped.Good packaging.
