Does anyone know where I can get one of the grey SD memory card stand ins? I have no clue what they are called but I had them when I first got my Sony PRS-505 but I chucked out the SD card standin when I put my own memory in the slot and now I switched over to Memory Pro Due and I don't want stuff to fall into the open slot of my reader. Also not sure if duct tape would be a safe material to use to cover the hole at the moment.
I'd appreciate any and all help/advice.
