Buy with confidence- TP Timber is cut, air dried, planed and kiln dried before being pressure treated with an preservative (Osmose or Tanalith E) which penetrates deep into the wood, right into its centre, rather than simply being applied to the surface, so our performance guarantees do not rely upon the annual application of a stain to the surface of the wood. Contains: TP Acorn Growable Swing SetAge: 6 Months+Batteries: Not required
