This entomology specimen collection jar is designed for students, educators, hobbyists, and field researchers who require a reliable tool for collecting and preparing insect specimens. Based on the traditional “killing jar” format used in scientific entomology, this handmade 16 oz insect killing jar is the perfect tool for effective insect collection. Each jar is carefully crafted with a pre-set plaster base designed to absorb and hold your chosen killing agent - no setup required. The wide-mouth design makes it easy to collect and preserve insects without damaging fragile wings or legs. It's reusable, field-ready, and compact enough to fit in your bag or kit. No chemicals are included with this product. This ensures full safety during shipping and allows the user to add their own. Whether you are collecting insects for taxonomy practice, biodiversity surveys, educational demonstrations, or personal study, this jar offers a durable, reusable platform for specimen preparation.
