Dear friends
My mother recently had a colostomy surgery; she is currently using
Hollister colostomy products. This is the only brand (very few models)
available in the country she is living. At this point she uses
Hollister drainable bag (44 mm, not precut). She says the set comes
with several bags and 5 stominals ( the thing that attached to stoma
with glue, I think we name it differently here in US).
I would really appreciate if you can provide me following information
to narrow down my search to find out what is the best product for her.

1) What is difference between one-piece and two-piece and which one
is better and why
2) She thinks disposable bag is convenient so which is the best
product for that?
3) Disposable = close bag?
4) Is there a product in the market right now which does not require
paste (glue),
5) in your opinion; using colostomy products for years which is the
best of the best(Without considering the cost, its for a mother,
mothers deserve the best).

Thanks you all
