I don't know if it will work in the Dymo Just know it takes a little practice to learn it just a couple words. You do have to press hard to get the emboss.
make sure you have it placed thru the machine correctly and it doesn't wibble wobble I learned this from their video...as I first had problems but everything worked out perfectly and I use mine all the time and love it. AGAIN just make sure you have it threaded thru you machine correctly and make sure it stays straight when you punch.....and it does take a firm punch....I hope I helped and good luck!!
