When introduce to the ostomy procedures I was more overwhelmed with trying to use the scissors that come with the kit they give you flat flange and a clear bag and that was pretty overwhelming once I found the soft bags with the cloth and the charcoal vent and the velcro everything got a lot easier except for cutting those scissors are awful I don't know who can use them and make a smooth cut all the way around I'm pretty good with stuff like that and that was almost impossible and the pre-cut ones were just not quite me I was in between an oval that's when I started cutting on myself with a punch self-made and my life ever since then has been different nobody has to ask is this good is that right if they're doing it for you one hit with the hammer maybe two if they're a little weak and it's done hope somebody will be able to use this technique understand what I'm talking about I know I use it every time I will never go back to those stupid scissors but that scissored edges look like a chainsaw had cut it out intimidating doesn't work well with one piece if I have to use a one piece I'll heat my tool and just melt through real lightly from the back side and it'll just it's done I've tried several heated let it kind of melt through or just hit it and they just hitting it and stay in Sharp awesome so much time saved so perfect every single time one piece is a shower head off a old brass and the other is an old Flashlight had several but these are the best
