(Custom Prints) Happy Birthday, 50 Piece Assorted Color Plastic Test Tube Set with Caps and Cardboard Rack

My wife recently purchased these to use Caps seem to be the subject of many complaints. There were some people who didn't complain as well. Therefore, I decided that I would risk it and hope it wouldn't cause any problems. There is a HUGE problem with the caps. No one stays on after they leave. Only about 1 out of 10 might be able to do it. My first step was to force them on, then I thought about it for almost a minute. As a result of the tabs that seal the caps being too tight, the caps are slowly beginning to come off once you push down on them. Consequently, the top does not stay on for a significant amount of time. So this is a pressure issue. The bottom tab on my wallet was already a little bit pressed, so I cut off a small section of it to release tension. Next, I cut several snips in the top tab to relieve pressure there as well. In this way, the cap could remain liquid sealed without being able to release enough pressure to pop itself I believe it is worth the time if you would like to have a cap, just like I would like it. It will take about 5 seconds per cap. We are one week into the project and the caps are still on without issue. This is something that should be done by the factory and delivered as a functional product. The prices were cheaper than I expected, though, so I won't The product gets 5 stars but only 1 star for its.

I bought these for an adult slumber party I hosted, and they were a big It was a bit of a challenge to work the tops, but I was able to do it. The two women survived a night of alcohol and wild behavior with a handful of tipsy girls. That's a victory in my book.

It is not possible to fill them more than half way, otherwise the top will not stay in place. Filling this position is difficult. It's a good thing I work in a hospital because I grabbed a syringe with 5ml to use. Although the colors are interesting, they are also fun. I found the holder to be junk, but it worked. I wouldn't buy again now that I know about the fill and such, since it didn't work the second time.

Neither my kids nor I can get enough of these. Despite the fact that I filled them with Reese's Pieces and M&Ms In a way) with Mini M&Ms My goal is to make something with M's or something of the same size.
I have left overs, and I have several ideas. For a little gift bag addition, if not just for sweetness. However, they can also hold liquid because the seals are great. Choosing these test tubes was a smart choice for me considering their quality, yet not too high a price.

They were purchased for my boyfriend's birthday party, which was a Mad Scientist themed party. In my plan, I was going to use them to hold flavored sugars at the coffee and tea A cardboard tube rack is included with this kit - it is a joke As a result, I wound up having to pay a lot more for a pair of wooden test tube racks last minute since the racks were bent and looked cheap. The fact that they are plastic (no risk of shattered glass) and the colors are fun were two factors that I liked. I devised the plan to use each color of sugar to illustrate different flavors. Despite this, the lids would not stay firmly in place. first filled these test tubes with sugar, I'd cap one, set it aside in the rack, and 5 minutes later notice that the lid slowly worked its way away from the tube. For reasons of longevity, such as keeping them sealed in a children's goodie bag, I would not recommend buying these.

I used these at my son's mad scientist birthday party, and they were a big hit! In the past, I have filled them with skittles or M&Ms We used these as favors and decorations and the kids loved them! Ms topped them with the cap and we used them as favors and decorations. This is a much better alternative than glass because it's very colorful and made from plastic.

It's great that you get a lot for the price. However, the problem is that there are literally 15 or so that won't I don't plan to use them as much as I thought I would. I still think it's a good deal for the price.

I'm not sure if there is some trick to it or if there is something I'm missing. I like them except for the problem with the lids. This is a nice and colorful picture.
