Rock Rosin

Use in my gym bag. Better than chalk, less mess. Works great.

This rosin is extra tacky like it says, and it definitely gives you a solid grip. A little goes a long way, so the bag should last for quite a while. My daughter uses it for softball and it helps keep her hands steady even when it’s hot out. Great value and effective.

The best disc golf chalk bag you will ever use.

I live in Florida and was experiencing some slippage on the stock grips of my clubs, we have some substantial humidity here. Rather then re-gripping as the clubs are not that old I tried this product . It definitely improved grip and was a much cheaper alternative. I will say you do need to break the product up the resin inside the bag upon arrival. Simply leave it in the plastic bag and push down on a hard surface and you should be good to go. My bag is fraying slightly on the stitching otherwise I would likely say five stars .

I play darts every Friday at my VFW. We use the old wooden darts and red dart boards. Darts always slipping out. Bought this to see if it would help. My average has gone up and close out a few games now and then. Definitely will get another when this tanks.

Great bag of rosin rocks. Helped throughout the season to keep his hands dry and made out easier to grip the ball during pitching.

Surprisingly the small stones or rocks inside work pretty darn well compared to the one that I had before that I had lost somewhere, but these definitely are a bit on the stickier side and I was impressed by them so I think everything will be just fine.

This product does not really work for what I wanted. I do aerial silks and sometimes I need a bit of extra grip when my hands aren’t fully warmed up, I read some reviews on this and decided to give it a try after seeing mostly positives. I don’t hate the product but I don’t feel like it adds much to my grip after using it. Another big problem is the smell, it has a very gross smell that bothers me. I don’t think it’s the worst, just not the best either.

Bought this product to use for aerial silks, my hands have a tendency to slide way too easily on the silks. I wanted something to help my grip a little but didn't want to go with a rosin spray since those can practically glue your hands to the silks. Chose this one and I'm glad I did. It provides just the right amount of extra grip to prevent me from sliding while not overdoing so I don't find I'm relying on the rosin instead of my grip strength. 10/10 would buy again!

Buen tamaño, viene en roca, hay que golpearla para hacer le polvo, pero eso evita que se esparza por todos lados, ninguna queja

Using for disc golf. Applied like Pedro Martinez says: a couple slaps on the hand, some sweat or spit, then burn it in by rubbing your fingers together. Gives a squeaky grip on Champion, Z, big Z, Opto, Proton, ESP, and all the softer plastics(gummy plastics will be a problem[Cryztal FLX, ESP FLX], with too much grip provided[this is a great problem to have]). I've never thrown a baseball pitch, but I have some baseballs, and on my first try I was able to get my hands sticky enough to hold a baseball for 2 seconds, upside down. (edit: I tried mixing with sunscreen, and on my first go it could hold a baseball for 2 minutes, before I got bored and stopped) Most people in disc golf use magnesium climbing chalk, a dirt bag, or sawdust bag, but these aren't aggressive enough for me(hands worn smooth from carrying cardboard boxes). Spin rate is also very important in disc golf (it makes the disc carry straighter, longer, before fading at the end). If you spin putt, this may destroy your putt. I spush, so the disc doesn't ever stick to my hand. For anyone looking for general grip 1: a tiny amount of working hands lotion (used daily to keep your finger skin perfect) 2: magnesium for climbing (works best at drying sweaty hands, giving gentle grip) 3: rock rosin (not rosin powder, or mixed mag/rosin)(works best for adding pure grip/stickyness, but also dries sweat) That will get you set forever.

It is so amazing it instantly gives grip and it works amazing I would 100% recommended
