HiMo 10 Pack Liquid Pipettes Droppers Silicone 5ml Clear Medicine Eye Dropper for Kids with Bulb Tip & Clean Brush for Candy Mold, Gummy Bear, Gelatin Maker, Oil Science, Crafts Projects (10 Colors)

These haven't been used yet. But! THEY LOOK LIKE THEY WILL BE PERFECT FOR THE WATERCOLOR PROJECT I PLAN TO DO WITH A SMALL GROUP OF TODDLERS. ONLY WISH YOU HAD THE BASIC COLORS WITH BLACK AND BROWN TOO!

I initially wanted an extra dropper or two for handling paints. I do art as a hobby to include watercolor, acrylic, oil, and airbrush painting. These droppers have been handy for mixing my paints, mostly watercolor and airbrush acrylics, but one of them came in handy for some maintenance work recently. I noticed the front and rear brakes of my street motorcycle were spongy in feel, which meant the brakes likely had air and/or moisture in them. I strive to be a safe rider, so I didn't want to ride with compromised brakes. A simple explanation for those that might want context: Brakes such as ones found on many modern motorcycles have a reservoir of special fluid. When the brake control is engaged, fluid is drawn from the reservoir through rubber lines to a caliper that houses pistons. The caliper is mounted around a disc that's mounted to one of the bike's wheels. As fluid pushes the pistons out, the pistons press brake pads to the disc, which slows the disc spinning which in turn slows the bike's wheel. With that knowledge, I decided to completely purge out all of the old brake fluid from my motorcycle's front and rear brakes. This would have been a very timely process, slowly forcing fluid from the reservoirs through the lines and out of the calipers' bleeder valves. This has to be done so air doesn't get into the system. Realizing that I had ordered this pack of droppers when I only needed only two, I decided to dedicate one to this task and it helped a lot! I was able to safely and controllably draw most of the old fluid from the brake reservoirs using one of these droppers, pour in fresh brake fluid, and purge the rest of of the old fluid out through the bleeder valves. So again, these droppers have multiple uses, even if they are rather unconventional! I'm so glad I sprang for this 10 pack instead of just getting one or two. In terms of day to day use, I haven't experienced any quality issues with any of these droppers like leaking. Should I use all of these up and need more, I'll definitely get more!

We’ve been using these eyedroppers for all kinds of science activities at home, and they’ve been fantastic. Our 3-year-old grandson quickly learned how to use one while counting how many drops of water he could fit on a penny—he was so proud of himself! It’s such a simple, hands-on way to build fine motor skills and introduce basic science concepts. Next week, the different colors will come in handy when we experiment with liquid densities. I plan to assign each color to a different liquid so we can easily tell them apart. These are sturdy, easy to squeeze, and the bright colors make learning even more fun. A great little resource for early science lessons or sensory play—highly recommend for parents, grandparents, or teachers looking for simple, engaging STEM tools!

These droppers perform exactly as advertised. I gave 4 stars rather than 5 as it is far to early to assess longevity of the product. I do like the different colors as I can use them for different liquids. For example, white for bleach.

Excelente producto.

They works great for what we ordered them for. Holds a good amount of fluid, easy to use, and easy to clean!!! The color range was really nice to match with same color liquid and seem to be very well made.

Item was not packaged properly by Amazon. Send it paper bag with another item which damaged the box. Product seems ok.

What a great item to teach toddlers to sort colors, mix colors and learn about making new colors by mixing two together (eg. yellow, blue). They are very easy for children as young as 2 y/o to manipulate and for a child of 3-4 to actually produce drops (vs. a stream of water). This is a great fine motor development tool for any number of fun games. At age 5 or so see how many drops one can fit onto a penny--a lesson in surface tension. The uses for these are almost unlimited. I hit them for a few weeks and when I brought them out again it was like a new toy again. I highly recommend these for young children!
