Will tsa at the airport allow it through? one of the comments referred to it as a gel, and i did not think gels are allowed.

It's allowed. Go to TSA.gov- search for " passengers with Diabetes". Here is what it says...Liquids, gels, and aerosols are screened by X-ray and medically necessary items over 3.4 ounces will receive additional screening. A passenger could be asked to open the liquid or gel for additional screening. The TSA officer will not touch the liquid or gel during this process. If the passenger does not want a liquid, gel, or aerosol X-rayed or opened for additional screening, he or she should inform the officer before screening begins. Additional screening of the passenger and his or her property may be required, which may include a pat-down. You have the option of requesting a visual inspection of your insulin and diabetes associated supplies. We always recommend that you bring a letter from your physician stating that you require the medication that you were bringing with you....And, that it needs to remain cool.

Will this fit an epi pen?

These are great for epis when it is hot outside! Unfortunately, the newer epis are a weird shape and don't fit as nicely as they used to. You used to be able to fit 2 in this size.

What are the dimensions? want to fit a norditropen gh pen

The inner dimensions of the Duo FRIO are 3.5" x 7.0 - usually enough to carry two medication pens.

does this have slots for each pen? or is it just open?

No it's just open and for the pens it's hard to have two in there. Just too tight when the beads are full of water.

Good but costly due it being an imported item.

Using it for my compounded LDN vial and also for glaucoma eye drops vial. Satisfied with the product and i keep it in my dehumidifer accessible room with ambient humidity of 40%. I soak it in ice cold water at the time of reuse. Not sure if i can generalize its applicability to different humidity levels like the highly humid south indian weather.

Very Disappointing, No Cooling at All

Very Disappointing, No Cooling at All I purchased the FRIO® Individual Insulin Cooling Travel Wallet (Burgundy) hoping it would help keep my insulin cool during travel, but it turned out to be completely useless for me. After soaking the inner pouch in water, it only swelled up—there was no cooling effect whatsoever. It basically works like a showpiece and offers zero practical value. Definitely not worth the money, and I would not recommend this product to anyone who relies on proper cooling for their insulin. Overall: Zero value for money.
