Refills are just like regular PixelPads but without the sturdy paperboard backing. Previously when you purchased a PixelPad it had a hard back, and when you ran out of pages you could just stick a refill on the backing and keep on sketching.
We've decided to discontinue the refills and just make all the pads with a solid backing. If you don't mind having a pad with a thinner back we'd like to offer the refills to you for a discount.
If you want more than 1 pad you can change the amount in your shopping cart.
