I have been buying enema toys for 30 years and developed quite a collection. Some items have been thrown out due to severe wear or breakage.
Rexall -- 2 quart open top latex bag -- this is what I took to college. A two quart douche bag was common and I didn't have to explain anything to anybody.
Sherema -- one gallon red rubber and yellow rubber bags and nozzles -- my first gallon bags and 32 Fr colon tubes, got them in high school, used them at home
Bard -- had several original latex double balloons -- good retention nozzles until the latex got old and rotted.
Rusch -- six or seven double balloons and a dozen colon tubes 36 Fr to 48 Fr -- wanted retention nozzles these are good. NOBODY makes better red rubber colon tubes. Haven't had to replace any in 20 years they are that good.
Noz-Wiz -- a few specialty nozzles, some of unimaginable size made of delrin. Everybody needs supersized and fancy nozzles.
Optimal health -- one 6 quart open top latex bag, one Olympia 5 quart closed top bag --purchased out of curiosity and two JBL bags, one with a control valve, one without the valve got a lot of use for a few years then they both broke. The 6 qt latex bag rotted and broke.
Klystra -- two silicone gallon bags and nozzles -- for major use, had five 500/250 cc double balloons and four 750/250 cc double balloons. The 500/250 cc balloons are better. Their bags are great.
Paris -- one 3 quart closed top bag -- purchased out of curiosity, I could squeeze the bag for added pressure if I wanted.
Amazon Rubber Company -- NOT amazon dot com, for heavy rubber hoses many years ago.
McMaster-Carr -- tubing and hoses for home made silicone colon tubes in large sizes and large diameter hoses for custom made colonic irrigating system connecting to the shower thermostat for continuous colon irrigation just like a closed system colonic machine.
My Husband -- who did stainless steel welding to make a one inch ID diameter colonic speculum and obturator for the irrigating system he built. NOTHING clogs that speculum! 😁 It was hard to use by one person because you needed to be able to remove the obturator and connect the waste hose while it was inside you. He also made similar speculums from white PVC pipe (3/4" ID) when I told him the stainless steel one was heavy and I was afraid it would crack or chip tiles and fixtures in the bathroom when we moved into our present house. I like the PVC one better because I am able to insert that without an obturator so I don't need any assistance using that. That one hardly ever gets clogged and I like the lighter weight if I wanted to change my position during the colonic.
Home Depot and other hardware stores -- hose barbs, connectors, squeeze bulbs and other accessories
Our BDSM equipment room looks like a meat locker with all the stuff hanging!
I'm probably forgetting some.
For some reason I have not yet ventured into the siliconenozzles.
