This MCAS card has a simple overview of mast cell activation disorder on. It provides a simple and effortless way to explain the basics of this little-known condition.

For more information on this disorder, have a look at the website of Mast Cell Action – a UK based https://www.mastcellaction.orgcharity.

This card says "I have mast cell activation syndrome (MCAS). Mast cells are part of the immune system. Mine react too easily. This can cause pain, fatigue, flushing, itching, rashes, inflammation, vomiting, and for some people may cause anaphylaxis which can be life threatening. These reactions can be caused by foods, smells, exercise, temperature changes, and emotions. It affects everyone differently. Reactions vary and may be occasional or many times a day. Severity of symptoms and what causes them changes over time."

This download is a pdf with 3 A4 pages - the first is the instructions for making the card, the second is the plain version of the card, and the third is the striped version of the card. The cards should print in size A7 (74 * 105mm).

(This will result in finished cards that match the size of the physical Stickman Communications keyring cards – approx. 110x80mm.)

Choose the page you want to print, and print it (Most files have 3 pages: the instructions, a plain version, and a striped version - however some designs are only available in plain). Print the relevant page on A4 paper or thin card. - make sure it’s set to ‘print actual size’.

Cut the card out along the solid black line.

Fold along the central dotted line to create a front and back.

Use laminated pouches that are 110 x 80mm, laminate your cards. Or use a larger laminating pouch and then trim the laminate to size leaving a 3-5 mm overhang of laminate all around the edge to seal it.

If you have trimmed the laminate to size, we recommend rounding the corners, as otherwise they can be quite sharp.

Using a hole punch, make a hole in the top left corner to allow for attachment to a keyring/lanyard.

Please note: We have had to stop all international shipping due to changes made to tarrifs and by Royal Mail. We are working to create download versions that will be available worldwide.
