A,P,AND P IS 4 INCHES TALL X 3.5" WIDE H AND Y ARE 5.75 TALL X 3.5" WIDE VALENTINES IS 10.5" X 1.5" All our signs are handmade AND we are a family-owned business since 2011. All our blocks are made from real wood 2x4 boards that do have knots however we try to sand them out the best we can so with that said no block set is alike. We believe this adds character to our blocks. We cut each board to the size ordered then paint and sand each one before they go over to the screen-printing room.
