This deep pine box will fit our 9x12" frames (all frames with code 100 up to 199). Please add this item to your shopping basket if you wish for your frame to be deeper than our standard 46mm deep box frames. We will make the depth of your frame at 70mm if you add this to your basket and your frame will NOT come with our standard 46mm back box. The extra cost is for materials and labour. Do note, if your order contains only this item, then only this item will be sent to you! You need to purchase from our box display frame range if you want a frame along with this deeper box. Do contact us if you are unsure about anything!
