Plasdent Excellent Crystal Impression Trays, X-Large Lower, Clear, Perforated, #X2, 12/Pk

The Plasdent Excellent Crystal Impression Trays are clear, disposable trays designed for use with color-changing impression materials. They feature anatomically rounded edges for patient comfort, a back retention rim to minimize gagging, and occlusal ridges to prevent bite-through. The non-slip handle with finger rest is marked for easy size identification, and the perforated design aids in impression material retention.
