The cork base lining provides friction retention of each slide without adhesive contact — slides seat cleanly in individual positions and release at the destination without label abrasion, coverslip disturbance, or staining reagent transfer between slides. The rigid styrenic shell provides structural protection against the compressive and impact forces of postal and courier handling that would crack bare slides in envelopes or bubble-wrap packaging.\u003c\/p\u003e \u003cp\u003eThe blue shell color supports visual batch identification — blue slide boxes are used in histopathology programs to designate tumor board case sets, IHC panel batches, specific consultation types, or accession date batches in multi-box storage and shipping systems. The 25-slide capacity suits the typical consultation case set size — H\u0026amp;E plus 4–6 IHC stains across 5–8 case slides — providing sufficient capacity for a complete case set without excess empty positions that create slide migration during transport.\u003c\/p\u003e \u003cp\u003eAt $48.39 per 20\/Bag — $2.4195 per box — the delivers professional slide protection at a per-box cost that supports single-use-per-consultation-case adoption for pathology practices submitting 5–20 consultation cases per week.\u003c\/p\u003e \u003ch2\u003eTechnical Specifications — Caplugs® Evergreen \u003c\/h2\u003e \u003ctable\u003e \u003cthead\u003e\u003ctr\u003e \u003cth\u003eSpecification\u003c\/th\u003e \u003cth\u003eValue\u003c\/th\u003e \u003c\/tr\u003e\u003c\/thead\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd\u003ePart Number\u003c\/td\u003e \u003ctd\u003e\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eCaplugs Item #\u003c\/td\u003e \u003ctd\u003e2585811B10E1\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eSlide Capacity\u003c\/td\u003e \u003ctd\u003e25 slides\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eSlide Format\u003c\/td\u003e \u003ctd\u003eStandard 25 × 75 × 1 mm microscope slides\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eBase Lining\u003c\/td\u003e \u003ctd\u003eCork — friction fit, no adhesive contact with slide\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eShell Material\u003c\/td\u003e \u003ctd\u003eStyrenic Thermoplastic\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eColor\u003c\/td\u003e \u003ctd\u003eBlue\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eClosure\u003c\/td\u003e \u003ctd\u003eFriction-fit lid — secure without latches\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eSterility\u003c\/td\u003e \u003ctd\u003eNon-Sterile\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003ePack Size\u003c\/td\u003e \u003ctd\u003e20 \/ Bag\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eReorder Unit\u003c\/td\u003e \u003ctd\u003eBag of 20\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eApplication\u003c\/td\u003e \u003ctd\u003ePathology consultation, slide mailing, IHC panel shipping\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eCountry of Origin\u003c\/td\u003e \u003ctd\u003eMade in U.S.A.
