100 Additional Slot File Numbers. Need higher numbers than 200? You can now order additional strips and add higher numbers to your slot file. Numbers are now available up to 500! Select item to choose number series.

You will need to order either a 100 or 200 bin slot file and then order these numbers separately. Your slot file will come with the lower numbers already on, and you will need to remove those numbers and add the higher number sequences to your box.

Note: Coloring of number strips may vary, (usually white or yellow).
