I am pretty surprised given that for years this product set is highly recommended by pig owners around the world but yet no company has ever sold it in the purpose nor has any shop sold it locally to me or others.
Only thing i can think of is that its not a good as product as many think, and to be honest its pretty costly for what it is, my current pen cost me a whopping £14 start to finish. and its 4x2 (8sqft) buy even if i had brought the ply i would only be adding £22 for an 8x4 sheet . Overall it should have cost £36.
The new one I'm planning to build will more then likely be double the cost around £60 with a sheet of 5mm tempered glass as the front.
The cubes are pretty expensive when i looked around, (screw fix etc) and to be fair not all that 'secure' the way they are clipped together in my opinion.
I'm not sure if this has be discussed in the past but obviously pet shop cages are not very good, but there must be pro's and cons to a c&c cage over a wooded constructed one.
I just went with materials available to me hence my low cost for a large secure pen. Maybe this should be discussed further to get a definitive answer?
I'm not a carpenter my skills are using fibreglass, it took 2 days to build using basic hand tool's, tape measurer, jigsaw tapping screws, screw driver, hand drill & a hammer.
Pen built in 2 days rest of the week was waiting for the protective stain and varnish to set.
