Made from 3mm customboard the 6x 8 inch (151 x 203mm) standback will last the distance.

The stand on the back is placed in a way that your photoframe can stand both ways, landscape or portrait.

The stand itself will NOT bend over time as some cardboard stands do.

Please note: when receiving the standback(s) you will notice the stand itself is hanging over the back quite a bit, this is done because there are many different  width frames and the stand needs to hang over a certain amount so it stands up at the right angle.
In the case of thinner frames you will need to trim the stand edges to give the correct slope to the frame when standing.
