PerfectKeep the Hard case the items were delivered in then cover the inside with a couple pieces of bubble wrap for measuring liquids

No lo califico como excelente porque a veces tiene fugas, sobre todo los de medición más pequeña, no sé si por la parte de arriba que es bastante débil o por qué será, los de 5ml y 10 ml son excelentes. El cepillo grande no entra en el de 5ml, pero sí en el de 10, a veces, por esta razón, se debe usar el pequeño y eso hace que no quede perfectamente limpio. Los compraría nuevamente

Product as described. Fair price quality items

I got 2 different sets of these. This brand is shorter and perfect for my needs - retrieving and dispensing vegetable glycerine from a 32oz glass bottle. I'm using these to mix ecig juice. Started using coconut based vegetable glycerin that comes in a glass bottle.. since 8 can't squeeze it out, I needed some long sturdy droppers capable of drawing up 10+ ml.These have great suction and operate easily with one hand. One full squeeze of the bulb draws vegetable glycerine above the 10mp line. Exactly what I was looking for!

These pipettes are accurate enough for what I need them for. However, the bulbs are too small for the 2 ml and 10 ml pipettes. Using the red bulb for the 2 ml pipette, I could only draw 1.64 ml. Using a blue bulb for the 10 ml pipette, I could only draw 8.2 ml. I had to resort to mouth pipetting for the full 2 ml and 10 ml pipettes - not a huge deal, as I'm pipetting water, but I would not want to do this for liquids that I wouldn't want to risk getting into my mouth. Had I known that the bulbs were not large enough for the 2 ml and 10 ml pipettes, I would not have ordered these.

I'm a soap and candle maker, and go through a lot of disposable pipettes in a month. I hate the plastic waste, so when I saw these I wanted to give them a try. They are a wonderful too and hold up to the caustic materials I work with. Also, the markings are fairly easy to read (although my old eyes can have a hard time with ".X" readings. I think it would be helpful to mark the fractional amounts with a zero in front (e.g., "0.X") so that it's a little easier to read. That's my only complaint though. These are great, come with little brushes for cleaning, and don't add to the plastic pile.
