The inserts are hard to get in, but you have to just push until you feel it puncture.The smaller pen didn't flow only after I reinserted it and then shook it. Only worked for a min and quit again. Due to the shaking it of course left in in the cap.Insure if it erases because there is no eraser, unless I'm blind...?So only one worked and I have no clue if it erases until I find out if my frixion pen eraser is ok to try and use.The sellee got back to me and said, sorry this pen doesn't come with an eraser. Hum...Then how do you call it erasable?And not even an offee to replace the pen the doesn work, so I've changed the rating to 1 star.Don't buy these junk pens.
