Foam inserts are a useful organisational accessory particularly for storing delicate equipment such as glassware. They are cut to fit a shallow F1 tray or deep F2 tray and can be used to store up to 30 calculators. There is also the option for a customisable foam insert for those irregular-shaped, delicate objects. The foam inserts are ideal for when these objects need to be carried around a learning space without getting broken or to immediately visually identify when one is missing.
