Holiday strolls by the sea often result in abundant harvest of natural souvenirs - pebbles, shells or amber. Sometimes it is possible to find fragments of ropes from fishing vessels or colorful pieces of glass polished by the sea waves. Items found on the beach impress with their beauty - the stones are usually colorful, beautifully shaped by sea currents, taking forms of flattened balls or irregular, rounded shapes, shells occur in countless varieties of color and forms – flat, crinkle-cut and spiral.
