Overall, I'm fairly pleased with this punch- it's very sturdy, it punches out sharp photo corners from cardstock and regular weight paper with a perfectly creased/embossed folding line. It's essential for making your own "old-school" style photo corners (meaning, not the ones that are decoration, but corners that actually HOLD a photo in place on a page).There's two things I don't like about the punch- the first is that because of the embossing aspect, the bottom of the punch isn't open like some of the other Martha Stewart punches. So if you want to get a precise area of paper in the punch for the corner, or use paper resourcefully to get the most punches from a sheet, you have to guesstimate where to punch.Also, you have to put in pattered paper upside down to get the photo corner right side up (so that the embossed fold is in the right direction).Also, the photo corners are fussy. The back edges don't quite meet up, so there's no easy way to seal the photo corners and adhere them to a background paper before inserting your photo into them. I wound up just leaving them flat, putting glue stick all over one side, and then folding them over the edge of the photo. It took more work than I expected.Overall, I am pleased- I wanted to be able to do a little "old school" scrapbooking (mounting photos on a page) as well as inserting smaller pieces of artwork into a larger sketchbook, and this punch helps me do that.I ordered this because the other low priced option on Amazon ships from Japan and I wanted it sooner. It is adequate in that it sharply cuts rounded corners. Downsides are: it only cuts one radius, and it is difficult to align the paper correctly (you cannot see the paper in the cutter and the alignment guides are too short for easy alignment). The result is thatif the paper is even slightly out of alignment you will end up with an over cut and notch on one side of the cut. Later I bought the Sun-Star Kadomoru cutter on Amazon and like it much better because it gives a choice of three cutting radii and is slightly easier to align. If you do a lot of this sort of thing in binding sketchbooks you might want to invest in a professional model (~$200+).Super easy to use, with extremely smooth punching action, plus versatility as it will not only make a beautifully placed corner butterfly punch (which lines up perfectly with slide out guide arms), but also, with just two minor snips, it can be turned into a freestanding butterfly, ready for placement on your paper, canvas, card, or scrapbook page with a tiny glue dot. The butterfly is quite delicate looking, but looks are delightfully deceiving in this case, as it holds up quite nicely, having generous edges so sturdy enough for multi-handling whether you are repositioning, glueing, floating in wax, or making a transfer.If you find other uses, or have any tips or hints, won't you please let me know?Compare with the larger MS monarch butterfly punch which I have also reviewed. I've never used one of these before and I expected it would be simple to punch out a rounded corner, but it seems like I have to place the paper in the right spot otherwise it doesn't make a clean punch. Now I use it upside down so I can see that the paper is lined up and that still doesn't always work. It could just be me. It does feel like a good quality though.After purchasing photo corners from different sources and being disappointed I ordered Martha Stewart's Photo Corner punch. I'm very pleased with this punch. It creates nice clean photo corners and it's easy to use. MS photo corners are medium size and I like the fold lines that produce the look of the original old photo corners. I've added an image for those that would like to see the size of the finished corners. I like the ability to make my own photo corners so much that I also purchased the larger EK Success Paper Shapers Large Photo Corner Scallop Punch. The EK punch creates lovely photo corners, it doesn't have fold lines, it is much larger and punches both corner options each time you us it. I'm very happy with both of these punches.Ordered 3 & used them to complete Wedding Programs for my daughter's wedding. They worked very well when doing 1 sheet at a time. I wish they would have worked better with 2 pages since we were gluing 2 sheets together. Would recommend buying this item with the knowledge that you can only punch one page at a time. FYI: we were using card stock craft paper.This corner punch was exactly what I needed when making and sending out bridal shower invites. Does a great job with rounding the corners (exactly like it's supposed to). The cardstock I was using was somewhat thin (thicker than standard printer paper though) and if I tried to punch more than one page at a time it didn't work too well. Not sure how well it would function on thick paper but it was perfect for my needs.I really love Martha Stewart products, particularily her punches. There is a slip enclosed with each punch that gives paper size dimensions to use....You must follow these to get that perfect. You may have to play with the punch and the around the page punch to get the hang of just where to line up the paper. With a little practice, you have a really cool outline idea. I use a lot of shaped flowers from Susan Tierney and Cottage Cuts die-cuts which are pansies. All of these together produce a really special product, and the people I give them to are always impressed and thankful for a hand-made product.It arrived quickly and in perfect condition.It is absolutely perfect to punch trough paper and heavier card (80mg maybe a bit too flimsy).I have used it on several 100s of pieces of paper and it still works perfectly.Well worth spending a few extra pounds on, especially as it is rare to find a butterfly corner puncher.Really like Martha Stewart's punches easy to store because of the fold up sides and really nice and easy to use.What a fantastic little cutter for corners. So easy to use and fold over the edges. Love it :)makes superb corner alternative for my cards and notes, very easy to cut and use and very happy with this buyFantastic, really makes my project look professional. Excellently packaged and very quick delivery
