This revolutionary new tapered "sleeve weight" provides excellent deep pressure input to forearms; increasing kinesthetic feedback and sensory awareness. A very versatile alternative for those who need the extra feedback during handwriting, but aren't able to tolerate a glove. Made of durable black lycra that is double-stitched for strength and filled with lead-free steel shot. You'll find a ton of uses for these!
