Before all the technology there was the MAGIC MULTIPLIER by Apex and the Multiplier pen by Universal.  With just a twist you can multiply numbers on each of these. Both need refills but the twisting and multiplying works on both. The Apex on has a little paint loss (see close up) and some of the numbers on the one by Universal are fading but you can still read them. Overall just signs of normal use.  They are fun novelty pens and a must have for any collector. *** BUYER TO PAY $5.00 SHIPPING IN THE U.S.   ****
