A beautiful half insert (approx half the size of a standard large trofast insert to fit one end of the 40x30 trofast trays 

Clear acrylic with a 5mm clear rainbow glued to the insert (can do the rainbow in black or white if you prefer, so please use the notes to specify if you would like that) 

The insert comes with thin coloured strips so you can build your own rainbow by placing the pieces in the correct spaces. These pieces are transparent so work wonderfully on a lightbox 
If the insert is wet, the pieces stick which is great if you want to lean it on a window ! 

PLEASE NOTE: The pieces are thin, so we don't recommend them being used with younger children who may be a little more exuberant ! 
We have added the option to buy spare rainbow strips at a later date if you need to replace any 
Or we recommend you could glue them into the spaces (any clear contact adhesive) 
 
The insert has multiple sensory play options 
Coloured sand (We include small sachets of all 6 colours free of charge)
Pom poms, gems and other small parts
rice, great for early years scooping and playing
coloured water. (tip is to add droplets of food colouring to each part first, then the child can slowly add clear water using a dropper and watch it magically change colour!
Use over a lightbox for a wonderful sensory play 

The insert comes with two holes, perfect for storing droppers, scoops or funnels (we provide a free random ONE item. This will vary depending on what we have in stock)
 
Simply rinse any coloured water, or sand away in UNSOAPY clean water 
Excessive use of soap may eventually break down the glue, so clean water is best 
 
Please note as the product is clear, you may be able to see glue marks along the seal of the rainbow, but this is minimal and we do offer the option for opaque white or black if you prefer
