These postcards (Avery 8386 Matt White Postcards) do the job well. From the other reviews, I've noticed some people having trouble in ways which may be user-error.First, I'd like to point out that the product listing may include other versions, so this review does not apply to them. There are variations which are glossy, sized differently, or position the post card differently. Be careful of which one you are looking at.Second, these post cards are finely perforated, but you have to follow directions. When viewed from the side labeled "Front Side," fold the perforations away from you first, then towards you after you have fully flattened the perforation. If you do that backwards, you may end up with some tearing which makes the edges look more ragged. These are do-it-yourself postcards so you shouldn't expect the edge to look like it was cut with a razor, but at least use it correctly so it doesn't look like a torn coupon.Now, on to what I like about this particular version...The print quality on these when using my Brother laser printer is good and complete. Some paper types (glossy, for example) may result in printing variations which don't look good because the toner may not adhere well to glossy pages. This paper is not glossy and does not have this problem.The postcards are arranged so there is a half inch between them. This allows you to print over the edge of the postcard so it does not have to have a margin. This is a super nice touch which isn't available in most other versions. The down side is that only two postcards fit per page. If you want four per page, you have to go with a version that doesn't allow for edge-to-edge printing.These postcards are fairly heavy at 230 g/m2 (around 155 lbs). That's much thicker than premium copy paper but not as thick as a standard business card. It feels like a typical thickness for a postcard. There are other versions (even by Avery) which are thinner, so keep this in mind when you're shopping! You can get cheaper cards but they might be thinner and feel flimsier.Okay, now for the not-so-great...I can't fault Avery for this because their card measures exactly 4"x6" according to my ruler, but I had to adjust where I print on a page in Microsoft Publisher to treat the top edge of the top postcard as being an eighth of an inch higher than it should be and the lower edge of the bottom postcard as being an eighth of an inch lower than it should be. This treats the postcards as if they are actually 4 1/8" x 6" rather than their true dimensions. Otherwise, the graphics on one postcard print lower than the other. I'm not sure how this happens, but I assume there is some sort of scaling going on (even though scaling is disabled). I print arrows along the edges of the page where I believe the breakaway lines should be so I can confirm that what's on my screen will match what's on the page and I recommend you do the same. If you put the alignment arrows close enough to the edge of the page, you won't see them on the postcard anyway. Keep in mind that every printer will print some pages a little higher or a little lower, so these alignment marks really just help you confirm the relative dimensions of everything. Always allow for about an eighth of an inch of variation from page to page, depending on your printer. This is the case even with professional printing services.Update (7/7/2020): I discovered the printer issue was the result of using the default printer driver from Microsoft. The size is now accurate after installing Brother's raster printer driver. This is only a problem people might run into if they avoid installing printer manufacturer bloatware. I didn't need their full install package, just the raster printer driver.So far that's it, I'll update this review if I think there is something worthwhile to say.
