Call or email all the different companies and get yiur free samples. I did that and that is how i found the coloplast product.
I had the SAME issue. I had to use a Convetec large (4in.) "Cohesive seal". I put he Holister barrier over top and center of the large (I can't stess this, they're not the smaller one's that simply just cover the base of the stoma) cohesive seal. Then I just trim away the excess Holister barrier/flange. Let me know if this help's, truly, I had the same exact problem.
