Purpose-built for butterfly and insect mounting: the large-size pinning board accepts specimens of varying wingspans, making it a flexible tool for hobbyists, educators, and researchers who need a reliable surface for preparing and displaying insects. High-density EVA construction: the board is made from durable, high-density EVA material that provides a stable, resilient surface for pinning and repositioning specimens without tearing or deforming over repeated use. Precision-crafted pinning surface: manufactured for accurate, clean results so specimens lie flat and symmetrical. The engineered surface helps preserve wing patterns and overall specimen posture for attractive, consistent presentation. Scientific layout to enhance appearance: pinning zones and surface texture are designed to highlight wing shapes and markings, improving visual clarity for display, photography, and study. Versatile compatibility: works with butterflies of different sizes and a broad range of insect specimens; suitable for use with standard entomological pins and common mounting techniques. Practical and reliable performance: resists compression and holds pins securely during drying and display, supporting reproducible mounting results across multiple specimens. Use scenarios: 1) Home collector: spread and dry butterfly specimens on a large, stable surface that preserves wing patterns for long-term display and cataloging. 2) Classroom or teaching lab: prepare specimens for demonstrations or student projects where consistent presentation and easy handling are required. 3) Field or research work: use the board as part of specimen preparation and temporary display during collecting trips or in small lab settings. What you get: A large entomological mounting board made from high-density EVA with a scientifically designed pinning surface that supports precise, attractive mounting of butterfly and insect specimens. Compatible applications: Butterfly specimen preparation, insect collection mounting, classroom demonstrations, amateur and professional display preparation.
