Bonjour, j'ai reçu ce produit aujourd'hui tel que prévu. Cependant le produit était ouvert dans la boîte et reste plus que la moitié du contenu

This is a great product and we've always ordered the 5lb from Amazon because it was a great deal until the price went up by $6.00. Not worth it anymore, Keson is cheaper.

If you are purchasing this for your baby gender reveal, make sure you have a clear shot to your tannerite. There should be no chalk blocking your shot. I put 4 lbs of tannerite in the center of a UTZ cheese ball container and filled 15 lbs of chalk around and on top of it. Five .270 WIN rounds later and no boom. It was like shooting concrete.Anyway, I did it the right way the next day with the drastically more expensive chalk from the local chain hardware store (same brand of chalk). 10 lbs chalk - 2 lbs tannerite made a huge cloud of blue.5 stars

Worked great for our gender reveal party!! Loved that it wasn’t so expensive like the actual gender reveal chalk powder you can get! We bought 15lbs of chalk powder and shot it off with 4 lbs of tannerite..did a nice cloud of blue smoke..turned out great for our babies reveal!!

We purchased 2 containers (10lb total) of this blue chalk to use for our DIY gender reveal. We separated the 10lbs of chalk powder into 5-6 quart-sized Ziploc bags and placed them around and on top of two 1/2lb containers of tannerite (prepared on-site). We read that the 1:10 ratio is what works best, and I would agree!We had a tannerite malfunction (still don't know what caused it) where after we shot the container through the front¢er, it didn't explode and the round popped 2 of our bags of chalk... The second shot went through the other container of tannerite, and went off perfectly! The photo I posted shows the aftermath of 10lbs of chalk with just 0.5lb tannerite (the other didn't work).I would absolutely purchase this chalk again, and would recommend it over the "color run" chalk that is more than 5 times the cost! If you're trying to get a lighter color, just mix in 2-3lbs of white chalk and it would look great.

Big jug of chalk line chalk...not sure what else to say. The price was right. The chalk pours out (or squirts out) of the cap nicely. Lays down chalk lines fine. I actually use this to mix in with drywall mud for repairing final imperfections...this way I don't miss light sanding any spot prior to priming new drywall.

Great stuff! We used this for our tannerite gender reveal! If your wanting to do a tannerite gender reveal this is the best stuff to get! The color is bright blue and works perfect for the gender reveal explosion! We ordered two of these so that we made sure we had enough for the 10 lb tannerite! Go big or go home!!!

This size is just perfect for refilling smaller containers. Price was better than the smaller containers and I already have the smaller container that I keep to refill. Irwin brand chalk color seems to bind to wood, drywall, or cement better than other brands. Color is dark and very easy to see.
