20 litre containers x20 (Abertillery NP13)

Came inside a shipping container I bought, so I don't know their history. I believe they have had engine oil, transmission fluid etc in them. I thought I'd post them on here in case anyone can use them before I take to tip. Collection from Abertillery or Penyclawdd near Raglan, or I may be able to drop off if you live somewhere I pass, eg Abergavenny, Cwmbran, Pontypool
