Opret Titanium Pill Container with Keychain & Necklace, Waterproof Pill Case for Emergency Aspirin & Nitroglycerin, Mini Pill Holder for Travel Purse Pocket EDC Accessory

The keychain holder is barely noticeable in my keys. Holds small pills and seems very durable.

Quality construction. It's smaller than I thought but still serves the purpose and doesn't take up room on you key ring

I bought my Micro Pill Fob 7 months ago and use it every day. When I bought it, it was $4 more expensive ($16.99) than it is now, and I was skeptical whether it was worth it. Now that I've used it, I can say that I am very happy with my purchase. In my opinion, the quality of the material and machining are very good. I kept four small pills in it for daily dosing, and it has worked perfectly for my needs. I like that it is small, not large or bulky, as I keep it on a carabiner with the rest of my keys. I also like that it does a nice job keeping the pills dry. Today, I used the 3rd and last O-ring that came with it. Besides keeping the pills dry, the O-ring also gives a bit of friction, so the top and bottom part of the container do not rattle or vibrate apart. My only issue is I would like to get some more O-ring seals, and I cannot figure out how to contact the seller. Having said that, I am still giving this Micro Pill Fob a Five Star rating given the quality is excellent, and I would say it has had very hard use.

It's a tiny little thing which is exactly what I wanted for carrying 1 or 2 aspirin just in case of anyone having a stroke or heart attack. People I've known were fortunate enough to have quick access when they had an event. One had a widow-maker and likely would have had massive issues for the rest of his life or died if he hadn't been given aspirin straight away. This has extra seals, attaches with a chain around the neck or to the keychain. and it looks like Stainless Steel so seems to be very robust.

My father needs to have a few medicine pills at hand, which he kept in his keychain inside a stainless-steel "micro" fob until its bottom part became loose and he lost the pills and fob. He asked me to look for a replacement. Since I wanted to reduce the fob's weight as much as possible (he hangs his 6-key keychain from the belt-loop closest to the right-rear pocket of his pants, so the repeated stress on such loop, either from normal use or mishandling, could loosen its stitching), and only a few tiny pills are needed, I bought this titanium micro fob weighing about half than his old stainless steel one.1. The holder, made in China by an unidentified manufacturer, is distributed by Shenzhen Ai Le Ju E-Commerce Co., which holds the registered mark Opret and sells in the US-Amazon marketplace through its subsidiary storefront since 2017.2. The material is described as titanium. This is not really very informative since there are six grades of commercially pure titanium, and at least 12 types of titanium alloys. Given its price, I do not exclude that this may be what is sold as "non-certified" titanium (either mill marked or not) or just a mix of pure titanium and titanium alloy waste melted together. The seller ought to provide such information.3. The holder is described as machined under computer numerical control (CNC) -- that is, under coded programmed instructions and with no manual operator. The outer dimensions in the second image from the top of this webpage are a bit different from those of the fob I received (shown in red font in my first figure), which is longer and narrower. The latter may be significant if wall thickness were fixed, as any non-trivial variation of the outer diameter will affect the maximum pill size allowed by the inner diameter. This should not happen at all under proper CNC. The inner dimensions, in mm, of my fob are in black font in the same figure.4. It came with a plastic O-ring already mounted on the lid and two spare ones. Completely closing the lid compresses the O-ring yielding a seal claimed to be waterproof. I tested the closed fob for water-tightness under a jet of water --it remained dry inside-- but did not try immersion, since being caught in the rain is generally more likely than falling in a body of water. Given such a claim, the seller should provide a proper water ingress-protection (IP) rating. The fob screws in firmly and tightly, and I often needed to hold the lid by its metal ring to unscrew the bottom part when testing it. It remains to be seen if it will continue to be tight with time. It is also unclear what is the useful life of the non-rubber sealing rings.5. Since the lid (shown in red in the first figure) has an inner diameter smaller than that of the holder itself (shown in black), and it screws on the inside threading of the holder, pills with a diameter under 11 mm but over 9.3 mm will be damaged by the lip of the lid if their stacked height surpasses 9.5 mm. In practical terms, the fob can hold two 325 mg aspirin round tablets --like those sold in the US by Bayer [imprinted BAYER] and Teva [imprinted ASPIRIN / 44 157]-- or two 200 mg ibuprofen coated round tablets, without issues. (If you travel abroad, keep in mind that standard-dose aspirins in Europe and some other places usually come in bigger and higher dose tablets.) Alternatively, plenty of low-dose aspirin tablets or of sublingual nitroglycerin tablets easily fit in the fob.6. My second figure shows the arrangement for my father, which includes a cotton ball to immobilize his uncoated pills and protect them from damage if the keychain were dropped or shaken around. To avoid introducing humidity (a valid criticism of cotton balls inside pill containers), the cotton is first kept in a closed plastic bag with a desiccant for a day before placing it in the sealed fob..

I was looking for a compact pill holder that I would have with me when I am away from the house for my dinner time med schedule. I put this on my key chain and hardly notice it. My pills are small so I can fit 4 in the container. It will probably hold 2 Aleve sized pills.

As others have said "a regular Aspirin tablet won't fit" Just snap the tablet in half and drop it in.I purchased this for nitro pills. It's much larger than I expected.
