½ INCH DRIVE DEEP IMPACT SOCKET SET 25Pcs (minus one) in Black Oxide Chrome Vanadium Steel. The set was used but is missing one piece, a 17mm piece. I've priced these on Ebay and I found a similar one, also in black, for £4.50 free postage if you need to buy one to complete the set. Bought and used by my father who has retired from working on cars. The set is in used condition. RRP £110, Britool do a similar set for £150 RRP.
