Product came bagged so if there was a incident it would not leak. The expiry date on this item is couple years away too. No issues with this product.
Well packaged, highly recommended
Purchased some methalyne Blue to treat my sick fish. I was super impressed that it was shipped the following morning and arrived to me less than 36 hours after I ordered it.And I really loved the little packet of mentos you threw in for me!
Good product
really does the job
