Le-Glue Le Glue Temporary Glue, 2 Pack – Non-Permanent Adhesive for Plastic Building Blocks, No More Messy Break-Ups – Safe, Non-Toxic Formula – As Seen on Shark Tank, Created for Kids, by a Kid

Great concept, poor execution. Glue just didn't hold. We followed the directions to a T, and waited ~30 hrs before handling any of the pieces. Pieces came right off with little to no effort. Glue was white and flaky, left a VERY visible white film on the pieces. At least it was easy to clean off. Dried the blocks off, and tried again with the same results. Going to use Gorilla glue on our Lego gingerbread house instead.

I am a Lego/brick flowers ADDICT. After a scare with one of my pets and a grocery store bouquet, I only put plastic flowers on my table. The drawback to a lot of the Lego and non-Lego flower kits is 1. Many of them utilize lots of dot pieces and 2 when you're trying to make an arrangement, they just crumble in your hands sometimes. This product helps keep small pieces in place, and can reduce "crumbling". It dries mostly clear unless youve really caked it on. Unfortunately, once it dries it eventually becomes very brittle, and if you handle pieces too roughly they will still come apart, but that's the tradeoff for it being water soluble. I have indeed "soaked" one piece after putting glue on, it fell apart, and I wanted to start over with it clean. Letting it sit in warm water with a tiny bit of dish soap for at least 20 minutes more or less removed all of the glue, so that does work exactly as advertised I plan to continue using this product. I also use it for some of my son's sets (he loves Mega Blok Pokemon sets) to keep together some of the builds more prone to losing pieces with normal 8-year-old level play, or for larger "play" builds like the Pokemon Training Stadium, so he (okay, let's be honest, mom) doesn't have to spend more time repairing than playing.

This glue is perfect for serious Lego style brick builds, especially with the cheaper bricks from China. It will not make the bricks more brittle like other glues can do. A small amount goes a long way. It is easily removable and does not leave a residue. Toothpicks are excellent for application. It can be used on other projects where you want a stable, yet not permanent adhesive.

Works well you can separate them if you want. Just put them in hot water.

A fairly decent value, I gave it 3 stars as this aspect in reality for me was basically neutral and didn't move my opinion either positive or negative. It is easy enough to use is the best way to describe it, you're either getting this as a collector which is probably less so than like most others you're getting it because you have younger new Lego engineers. Good luck trying to build a set with 1 set of over helping hands let alone if you have more. My son helps and I encourage him to with some and with glue it is just a little more difficult to manage and at a minimum doubles, if not more, the build time of any given set or structure. Fortunately I work nights a lot so when I'm off some more complex structures miracle themselves into existence overnight. That said it is easy to use with a little brush and I don't want to sound to critical on it being easy to use only that the extra time factor can be more than anticipated. As far as adhesion goes, it is pretty decent and probably better than my rating of it but prior reviews really had me expecting it to be a bit more durable than it really is. I mean I understand when The Hulk smashes, things are going to smash for me though some things were really just to simple to come apart through general play. It does a good job and for the most part does what it says, I expected a little more. All said I would recommend this to anyone with little builders as at the end of the day it does make structures more durable and holds things together better than they otherwise would. Cheers and most importantly enjoy the Lego time.
