I came across this 75% off uni-ball products from Staples. While great performers, Uni-ball pens tend to be a bit pricey so I was very excited when I saw this coupon. I picked up an 8-pack of the multi-color Vision Needle pens, regularly $13.49, for only $3.37. The packaging claims that the .7 mm needle point is stronger than the leading needle tip. I'll try these out on some the new notebooks I recently purcased from Muji.
