HaBeuniver 30Milliliter Precision Applicator Bottle with Blunt Tip Needle and Cap|14ga 16ga 18ga 20ga 22ga Blunt Needles|Oil Dropper Bottle, Glue Applications, Acrylic Painting, 8 Pcs

I've lent these out permanently to the pottery studio since they're so useful. The glaze gets stuck every now and then but otherwise they're perfect for Glazing fine lines. Also good for the wax resist., Love the variety of sizes. Might have to order again just for more bottles.

When doing electric/electronic repairs, I discovered that using a small applicator like this really helps control where the Deoxit goes. The plastic applicator tube is my go-to but the needle applicators might have their own use cases in general, just nothing I've come across yet. The smaller tube works for my needs. Even the smallest needle tip was dispensing the Deoxit too much/too fast for me, but I could see this being useful in other cases with different materials (getting IPA into hard to reach areas, putting lubricating oil onto moving parts or maybe drip some WD-40 onto squeaky hinges without the typical overspray, etc).

I originally bought these to apply CA glue (super glue) more accurately. But the bigger tips also work for smaller applications of wood glue. It'd be nice if the tips had a positive locking attachment rather than just a pressure fit on the bottle nozzles, but so far I haven't had an issue with one coming off while applying glue.

This kit is very handy for controlling what ever medium your using. You can reach into small places to apply glue or oil. I used one of the needles to fix some delamination on an oak chest of drawers. I was able to reach under the laminate and apply glue without further delamination. The wood glue flowed very well and the needle cleaned up easily and thoroughly when I was done. I will be able to reuse the needle if needed. Well worth the money........

I was very pleased with this product. The tips and applicators and bottles are easy to clean. The tips for sealing the bottles is an added bonus. They keep the paint from drying up. I am using these for fine lined application of paint in paintings. I highly recommend this product.

I have used the needles for applying glue into small cracks in chairs and woodworking projects. The small bottles are great for measuring 2 cycle oil in small quantities. I usually mix up my premix gas as needed, only about 1 liter at a time, so I need to measure 20ml of oil, and the small bottles have ML markings for 10, 20, 30, etc. The tapered plastic ends that you screw onto the bottles allows for very precise placement of lubrication so they are great micro-oilers for bearings and tapping threads without using too much oil.

I bought these for slip trailing engobe on unfired clay and that works great! I have also found they work very well for controlling underglaze application into pressed impressions on pieces where it is difficult to clean the glaze from areas you want to remain clean. Cleaning the fine holes is a bit difficult but easy enough if you blow them out with air.

Have used this to apply underglaze - it does want to leak around the threads, which is easily remedied with a bit of thread tape. Was only able to use it with the largest two needles, which applied a relatively large stream, not appropriate for anything but coarse mishima work. If that’s what you’re into, great; if not, not very useful. Leery of anything that uses needles on a slip-tip (jammed on) rather than a luer lock; needles WILL come off if apply more than a little pressure, limiting utility.
