Great drop checker, great price!
$5.50 here! Why pay $25 for the same drop checker sold in the U.S.
Long plastic pipette tube can be used to fill and empty after you 'mould' the tip to fit the drop checker - curve the tip using hot water to soften.

Very useful and easy to use, you can put de liquid with a syringe.
And was the best price that I found, the shipping was really fast, it takes only 8 days to Brazil.
Already recommend the product and de store for a lot of friends.
