Rock Rosin

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.

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

works good. keeps the hands dry. use it for golf.good gripping

I'm an amateur aerialist and got this to help my grip while on my hammock. the rosin itself works great, the fabric bag however is not the best - the stitching wasn't secure and a hole opened up at one end on day 1 of using it 😑 since the actual rosin does the trick, though, I'm going to transfer it to a plastic bag and hopefully that will work much better!

As an aerialist in recreational circus arts, grip is important for safety, and this provides. The packaging in a canvas bag makes it easy to keep neat; I keep it in a ziploc bag for travel and just reach in to squeeze it for application. Especially when woken up with a small amount of water or alcohol (i.e. hand sanitizer), the rosin is sticky without being too sticky. It's lasted well for me, too!

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.

I use this daily while playing pickle ball to keep my hand from being sweaty. I highly recommend it.

Cloth bag that its in gets cloged with pine tar when u slap it against the taper u know for that tacky dry pine tar u want

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.

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

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!

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