Well made, and accurate measurement.
This is a well made volumetric flask that accurately measures 10mL. Compared to purchasing at science supply shops, their price is reasonably good.

Great price, easy to break
Well made for the price and have been great for standards so far; BUT I did have 2 break just from a stir bar bouncing off rotation a bit.

Try them, you will like them
I love these things. I fill one with hydrogen peroxide and the other with alcohol. The really great thing about these is that when you need to soak something like a cotton ball or a q-tip, the liquid does not come rushing out like it would with an ordinary container, due to their design. When you have a cut or something else you need to treat, you will really appreciate them.

Great for the price
I've been using this for a few months now and have had no problems with cracking even with major sudden temperature changes. It's not super heavy duty, but I'm not a heavy duty chemist. It's sturdy enough for regular casual use, and great for making and storing simple syrup!

Producto con defectos
Un matraz me llegó con el tapón de vidrio estrellado, además el vidrio de los matraces presenta rayones que le restan estética. Todavía no los sometos a ciclos de calentamiento y enfriamiento, espero resistan bien.
