Photo Blocks 18mm - square
Square sizes (up to 6 x 6 inch) are free-standing.
Other sizes have the wall fixing attached. All have a vinyl black back.
Blocks are approximately 4mm smaller on both dimensions than print size to allow for easier mounting. It is best to expose 4cm of the adhesive first, adhere the print and smooth down the print whilst removing the remainder of the release paper.
Excess print to be trimmed after mounting.
