I went to Daiso in Eastridge Mall today and i found Instant Freeze Pack For Neck at the health section so i decided to buy it because its only $1.50 ^-^
So you use this freeze pack for your neck when :
playing sports (yah, i guess to cool yourself off after you're done playing sports. I wonder if you can put it on while playing)
doing leisure activities
driving
working under the burning sun
studying
relieving fever, headaches,toothaches, and sprains
At first , i thought its probably just one of those gel thing like those gel masks for your face. But after i opened the packet, I was a little disappointed because the cover is made out of plastic [-.-"]
To use this freeze pack.
1st, you look for the squishy side at one of the ends of the pack ( its squishy because it has water at that part)
2nd, You start to punch that squishy part like crazy O_O". ( it said on the back of the cover that when the water-part is broken, the chemicals mix with the water and blah blah but you don't need to know chemistry)
AND THAT'S ALL [^----^]
you will soon feel the icy cold touch of it after few seconds and yah :)
The cooling effect will last about 10 to 30 minutes. THE TEMP. CAN GO DOWN TO 24.8*F.
BUT, the duration may vary remarkably depending on the room &body temp and other conditions.
Conclusion:
To me, I don't think the freeze pack is worth buying since it's not re-usable. BUT other people might have different opinions.
And i didn't threw it away after using it, i didn't want it to just go to waste so i put the pack in the fridge. After about 5 mins, the stuffs inside the plastic froze into snow or something IDK O_O
( probably because of the chemicals).
So if you would like to try it for fun or something then just buy it ^--^
