Yuck E Ball Fidget
Great for fidgeting and strengthening!
Yuck-E-Balls are made tough with the thickest, seamless skin, filled with non-toxic gel. Small balls move on the inside. Extremely durable. Colours may vary.
Seems robust to withstand rough treatment. I certainly found it useful as I was trying it out before giving it to the child!
replacements for old stock, sadly they don't have a long "play life".
very good service, quick delivery
They do the job
