Adorama Black Trans-Mat, 7 1/2x9 1/2" Slide Presentation Board with One 4x5" Opening.

• These jet-black mats are extremely easy to use! Simply position the sleeved transparency behind the window and tape it to the back of the mat. For a more finished look, sandwich your transparencies between two mats. Mats are made of heavy weight mounting board. Although not archival, the sleeve in which you place your transparency should be for slide protection. Out side dimensions of the mats are mostly 11" x 14". This makes them easy to store in an 11x14 print storage box.
