Presenters at the Academy Awards will get a pricey thank you for ripping open the envelope and announcing winners on Sunday.

The Academy of Motion Picture Arts and Sciences has assembled gift baskets packed with at least $6,400 worth of luxury items each.

The Academy keeps details of the baskets secret, but some companies contributing to the packages say the final worth could be as much as $20,000.

Julia Roberts, Jennifer Lopez and Tom Hanks will be among the dozens of presenters in line for the gifts.

After the ceremony, they can sniff $400 bottles of JOY Perfume while relaxing in $160 Loveletters Loungewear spa clothes and sipping $100 samples of Mingcha Chinese tea.

Later, they can polish their smiles by cashing in $600 certificates for BriteSmile teeth-whitening sessions and shield their eyes from glare with $250 TAG Heuer sunglasses.

Presenters include Spider-Man co-star Kirsten Dunst, The Lord of the Rings supporting actor nominee Ian McKellen and Broadway star Nathan Lane.

The gift baskets reportedly include chocolate-wrap skin treatments, designer handbags, certificates for $1,700 shape-conforming mattresses, $1,600 Ebel Watches and $300 vouchers for Birkenstock shoes.

The Academy Awards will be telecast live on ABC from the Kodak Theatre in Hollywood.
