Concaves

[Mark Smyth]

I have concaves available.  They are £2.50 each plus £1.60 postage.  I can get two in a letter box box for the same price. 

Later this year I'll be offering bespoke concaves to fit the width of your nest box or other needs.  They be 8.5cm in diameter with a vertical edge 2cm deep concave. We'll be trying out ramped concaves with a 2.5 or 3cm deep concave

I really don't get the new idea of a flat bottom nest ring
