White Foam Board 20 x 24 x 3/16" (5mm) Inch, 15 Pack Acid-Free Foam Core Poster Board Sheets for Art, Crafts, Presentation, Vision Board, Signboard, and Party Decorations

Lined pantry shelves - great outcome.

I've seen a number of bad reviews about this product, but mine just arrived quickly and in perfect condition, with nice plastic corner protectors that did their job. I think some of the reviewers are expecting more from this product than it's intended use. These are great 3/16" foam core mats, which were surprisingly hard to find--most sellers only offer 1/8" think for white and that is often not sturdy enough. Also, all of the white mats I ordered are 3/16" thick, which is what I wanted, so I don't know why the title of the product includes the word "Many" in it: "Excelsis Design, Pack of 15, Foam Boards (Acid-Free), 11x14 Inches (Many, 3/16 Inch Thick Mat, White . . " To the managers of the company, I suggest you delete this word in the description as it sounds like many but not all of the boards are 3/16". I almost didn't order because of this confusing wording, but I'm glad I did. Perhaps you meant, Fifteen 3/16" Thick Mats. But again, great product!

Perfect for our needs. We have reordered. Great product for the price!

[See middle bracketed paragraph for what has changed in this review] From the advertising in Amazon it may look like they only offer Black, but White is a choice in the process of placing the order. I use a 3M spray can of contact glue to apply to the board and then I quickly place the photo, there is no second chance with the 3M Contact 90 spray, but it's quick dry means a good adhesion and no bubbles or creases so long as you are quick and exacting. There's also no adhesive wetness coming thru the print and once down you are done.[REVISION: See new photo. The 3M Contact 90 (TM) spray adhesive behaved initially as expected, and I have used it on 20x30 boards where foam was sandwiched between two layers as is done here. The sandwich this product uses either had too porous of layers lining the sandwiched foam or two thin. The photo which transferred flat initially began to show serious and unacceptable bumps and unevenness (see photo). It's reasonable to assume the fumes from the solvent based 3M adhesive continued to exude solvent vapors that passed through the outer sandwich material into the foam which dissolved/displaced, expanded, warped. I am absolutely certain the solvent used in the adhesive combined with the makeup of the outer sandwich layers to have a bad outcome on the inner foam. I will try to find a non-solvent based fast drying adhesive. These are of no use to me unless I find such a product.]They do make presses where you can dry-mount and have more surety of placement (assuming you perfectly line of the three pieces and closing of the press doesn't cause them to shift). but those presses are quite expensive and the dry-mount adhesive sheets aren't cheap and may be problematic to store depending on your climate. I find this board and spray contact cement a great alternative, but again, no room for a re-do if you don't place it correctly. Practice on a scrap board without the real photo until you get the knack of being fast and accurate in your placement.I spray the whole board then I lay the picture on at one end and then basically lay it down progressively until it's all down.

The boards are rigid and flat. The shipping was very good, the corners had extra cardboard protection. I couldn't have picked out better condition boards at a store. I will be using them to do jigsaw puzzles.

I liked the sturdiness. Using to wrap quilting fabric for organization. Several were very dirty. Cleaned best I could, still stained after all that would come off came off. Hopefully won't mess up my fabric over time. Some were not square, meaning measurements were off and didn't square up on ruler when cutting to size wanted. Since just using for fabric, measurement being off didn't matter for me. Excelsis was advised and they are looking into why they were so dirty, etc. Would have given a 5 if weren't so dirty. Need 5 more packs of 15 soon. Will still order from Excelsis, they seemed generally concerned about the quality of their product. Update on my review, Excelsis customer service is awesome. They gave me a refund for the portion of the boards that were a problem. I didn't even have to ask for anything and they advised they will check to see what caused the condition of the boards I received. I will definitely order the additional boards I need from them. Will give them a 5 star rating. Update: the second set of 5 pkgs of 15 I received, their were 11 boards that were a little dirty,No where near as dirty as the first set o bought. The problem with this set, the majority were very warped. The third set i just received a week ok, were great, no complaints. No dirty boards, not even the packaging was dirty like the previous two orders. I will still order more from them.

This is a nice product and was just what I needed. The problem is that it needed to have nice corners and no defects. I needed six pieces out of the bundle to be perfect. There were only 3. I did manage to arrange them so I can use a hot wire to trim them after they are fitted to the top of the table. While the damage was not real bad I am gong to have a few wrinkles where they join in some places. Over all I will make it work but for the price they should have arrived in better shape. One corner was missing the protective scrap piece the other three had and one had only a small piece of scrap hence the damage. Also one sheet does have a defect or blemish on its surface on one side. No big deal since I won't be using it. The surface is very nice and very smooth. Over time I guess I will find a use for the other pieces.

Items shipped, in good condition. Arrived on time, as promised. Everything went as represented and expectations were met 100%. Special care was made to protect the boards during the shipping process, and the packaging will stand up to reasonable wear and tear while in trantsit. Value for money? You can get these foam boards cheaper, but if you want acid free, which you do if you actually care about your project. So a very good value for money in that regard.
