For sale is a NRFB Tape and book called "Double Grubby" by World of Wonder. These are very hard to find NRFB. Please check back often as I am selling my collection and time permits and please do not pay for your item until I have sent you a revised invoice for the shipping. I am finding that the rubylane shipping amount is an estimate. I also only ship fed ex as I am finding it is safer and sometimes lower in price then using any other service.
