June & December Medium Specimen Bottles with Cork, Set of 16

Sixteen smaller cork-stoppered glass bottles — sized for the tiny finds that need their own jars to avoid getting lost: pollen, seeds, sand grains, small beetles, a single feather.

Pair with the larger 10-set and the Specimen Collecting Kit for a layered classroom collection: medium bottles hold the broad finds, smaller bottles hold the fine ones. A working naturalist's archive at child scale.

Educator notes: Useful for sand-and-soil studies, seed sorting, and the kind of pollination unit where children need to capture and preserve individual grains. Glass doesn't off-gas; will outlast any plastic substitute.

Specs: Set of 16 clear glass bottles with cork stoppers. Smaller size for fine specimens. By June & December. Ages 3+ (adult supervision recommended; glass).
