Plates of sturdy reinforced glass: brand new unused (Marston OX3)

Six plates of sturdy, reinforced glass, each one 47 x 31 cm. Clear to look through, greenish tint when seen from side on. Supplied for use in a kitchen cabinet but not needed, so brand new. They can be used for anything really, including creating your own greenhouse. The third photo shows them load bearing to demonstrate strength (the crockery is not on offer!).
