lot of partially used or new pads – will include at least 400 single sided sheets – between 400 and 450 sheets there may be more than 6 pads – there may be up to 12 pads – the pads may be thin. I sell these by weight (1 pound 10 oz is at least 400 sheets) – so you will get at least 400 sheets, usually more – but the number of pads will vary and the pads may be thick or thin and may or may not have cardboard on the back. If you buy more than 1 set, the 2nd set and additional sets ship free. You only pay shipping on the 1st set.
