stems and leaves.

• Seaweeds are photosynthetic organisms

• Each seaweed contains a wide range of

essential nutrients, including enzymes, nucleic

acids, amino acids, minerals, trace elements,

and A, B, C, D, E, and K vitamin complexes.

Hollywood Impressions Developed for customers by popular request from

ArtMolds' dealers, Hollywood Impressions is a

superior quality Dental Grade alginate with a set

time of approximately 3 minutes.
