Carrera20571 Curve 1/60 3-piece add on expansion accessory set compatible with Evolution, Digital 132, and Digital 124 slot car tracks

All tracks need LOTS of curves. These give you tighter turns, less space !TIP : CAREFUL when you push them together, the inside and outside edges are THIN !

Perfect

Sold as new but came loose in a brown box ? That seems dishonest to me. Just sayin .

Once you get into the hobby, you will want to add more curves and straights to your your track since most sets come with relatively short track length. The only downside is that extra track parts from Carrera are pretty expensive - I'd say almost unreasonably expensive. I suppose they follow the "Gillette" model to subsidize the starter kit (I doubt they are actually subsidized) and profit on the extras. Still... you will want to add to your track length.

good price
