A reward jar made from acrylic and wood, with brown and yellow acrylic tokens. 
Designed to encourage independent self care with regards to toileting. 
Sometimes children with Autism or other sensory needs find it difficult to understand the sensations of when to use the toilet. 
Those with ADHD can be so engrossed in activities that self care and toileting is not their main focus, ending in accidents or rushing when going to the toilet and forgetting essential hygiene.
These jars can be used to encourage positive toileting routines. 
Have a go, see if it works for your family.
