I have no idea if these are useful to anyone nowadays or not. If you need one, make me an offer. If it's useless, let me know to toss it in the recycling bin. It will probably fit in a flat-rate envelope. Instructions included. Shipping & Paypal fees, if any, to the buyer
Update: How about $15 delivered in the USA via priority flat rate envelope? Paypal fees to the buyer, if any.
