This is a bin bag. It’s a very clever piece of kit, it can fold or roll down very small, small enough to even go in a pocket !
Then it can make itself very big ! Big enough to hold all the rubbish that is left after your visit to, or your picnic in, the park ?
Unfortunately, the bags have not yet learnt how to fill themselves, so they need some help from us humans.
It really likes to be taken back home when it’s full and to be placed in your bin ??
Why not join forces with this clever bin bag and keep our beautiful parks clean and tidy.
Have respect for your surroundings, other people, children and wildlife !!
