This lens sucker kit is ideal for repairing and cleaning lenses and watches, mounting IC components, and handling small parts. The large suction cups create a strong vacuum seal on flat surfaces, suitable for lenses, while the smaller cups pick up tiny components from watches and integrated circuits. The suction pen allows retrieval of items from tight spaces while preventing fingerprints, smudges, grease, and stains. Includes 7 different-sized suction cups (12mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm) to accommodate various lenses, optical devices, watches, and IC components. Notes: 1. Stains, grease, moisture, particles, and dust may affect suction performance. Clean the surface before use. 2. Do not use on concave or convex surfaces. 3. Use only for intended purposes. 4.
