CoordiMate Self Inking XY Graph Stamp Clear and Red inch Measurement with EVA Pouch Packaging (CORD5)

These stamps are really cool, and quite useful. That said, I do have two complaints: (1) The ink is way too dark, and bleeds through loose leaf pages and composition book pages. This means my students often can't use the back side of their papers, so they end up using double the amount of paper to complete their homework. (2) The full price of this product is way too high -- so try to find them on sale, if you can. I got mine for around $8, which was totally worth it. But I would have been upset if I paid $15 or $20 and then discovered Problem #1 (above), which many of them being sold on Amazon and other websites are selling for. It's also a bit ridiculous to sell different colors at different prices, especially since it's just the plastic casing that is a different color, not the ink. All of them have black ink.

It may make me a geek, but the arrival of this stamp made my day. :) I love it. So handy for the kids and their math assignments. Just a simple grid with litte tick marks, no x and y labels - but that is good because you don't have to worry about putting it any particular direction on the paper. Just press down on the smiley face and - tada! I have seen other versions of this that are not self stamping, but this product deserves an A+ for convenience and time saved (plus it is refillable!) It creates a 2x2 axis layout with 8 notches for each side of 0,0 - and it works perfectly with graph paper (same size) if you want to pair it up.

It's really convenient to use. The bad point is the ink is so strong that you can even see it on the other side of the paper, so don't use it during the test. If this company can make the ink either red or blue and less strong; it will be a perfect product.

Works exactly as expected, but there were two main problemsFirst, the ink bleeds through paper. (Printer and graph paper)Second, when using it on graph paper, it is difficult to line up the graph with the paper’s lines.Because of these, I didn’t use it very much. However, the ink is bold and visible, it dries really quickly, and lasts for a long time.

I love this little gadget! Its so handy to use in order to make graph stamps, etc. I haven't had to refill it yet.. it's been about 2 months since I have bought it. Its super compact and I have recommended to many friends already.

Every math teacher should have one of those. Stamp works very well and has lasted a long time. I pass this around in class and my students LOVE it. Some have even bought their own. Would love to get myself a classroom set!

Works great and is going to make an excellent Christmas present for an engineering friend of mine. I hope it doesn't run out of ink too fast because my only concern is that I don't know how you would go about refilling it!

This helps me a lot with plotting graphs in my pre-calculus class. This has saved me hours doing my homework and made it much neater. Just make sure your graph paper is the same as the stamp that you have.
