- They are relatively cheap
- The plastic is the perfect combination of smooth for slip and non-metal for grip
- They are color co-ordinated.
Anyways, they aren't sold locally so on a lark I searched ebay. And found an auction the most confusing description EVER, but it looked like 7 sets were in the Lot. So I bid and ended up as the winning (read: only) bidder, and thus spent $28 for:
TWELVE sets of Lion Brand DPNs! The rest was cake :-)
