Do you remember these ads for the "Surprise Package" that used to be in the back of magazines like Popular Mechanics or Boys Life back in the 1970's and 1980's... oh man, do I ever!! I could just imagine the cornucopia of awesomeness that might arrive in the mail if I were to send them my $0.50 in the mail... maybe it would be the X-Ray glasses or the Smoke From the Fingertips gag or the Voice Throwing trick!! WOW, what possibilities for a young boy reading that magazine so many years ago! Well, I never did send off my $0.50 to find out what the big surprise was but I thought it would be fun to do this with our MakerGeeks friends (that's you by the way!) - so, here is the deal... when you order just pick the filament size you would like either 1.75mm or 3.00mm and we'll send you something REALLY good... could be anything, maybe a crazy color of PLA to Laywood or NinjaFlex to something that isn't even out of Beta-Testing yet. I also promise the the value will always be at or above the $19.95 cost you spend; and you'll be sure that what you receive is new, sealed and in good shape; no junk here - hey, that's a good sort of surprise!! Hope you enjoy as much as we do... now, if I could just get my hands on that voice throwing trick I could really have some fun with our shipping guys!! Please Note: Due to the limited supply and nature of this offer we accept no returns or exchanges; it's a grab bag of FUN so as my wife tells my daughter... "You get what you get, and you don't throw a fit..." ;) Have fun and enjoy!!
