Master Glue 2-Pack — Professional 1-Second Lash Adhesive

Master Glue 2-Pack includes two 5 ml bottles (10 ml total) of our fast-setting professional eyelash extension adhesive, with an approximately 1-second setting time and medium viscosity for precise application. Master Glue supports efficient lash services, with retention of up to 5–6 weeks depending on application, natural lashes and aftercare.

Key benefits

• Fast setting: approximately 1 second for efficient extension placement; setting speed varies with working conditions.
• Medium viscosity: controlled pickup for precise lash application.
• Working humidity: 30–70% RH.
• Recommended room temperature: 68–72°F (approximately 20–22°C), following our adhesive instruction sheet.
• Two 5 ml bottles: 10 ml total for professional lash services.

Preparation and storage

• Before first use, use the included red needle to gently pierce and remove the sealing gel at the nozzle tip.
• Shake well for 5–10 seconds before dispensing each drop.
• Store in the refrigerator before opening and return it to the refrigerator immediately after each client, following our product-specific instructions.
• The adhesive may be used immediately after removal from the refrigerator.

Application and environment

• Maintain a cool room temperature of 68–72°F (approximately 20–22°C).
• Avoid direct airflow from fans, vents or air conditioning blowing toward the working area.
• Keep the client's eyes fully closed throughout application.
• Apply extensions at least 2 mm away from the eyelid and avoid skin contact.
• Cleanse natural lashes thoroughly. If the lashes are slippery, use primer or bonder according to the instruction sheet and the preparation product's directions.

Finishing the service

• After completing the set, keep the client's eyes closed and fan for 2–5 minutes before allowing them to open.
• Apply Super Bonder after the service to support adhesive curing and retention. Follow its application directions: wait 2–3 minutes after the final extension, dab a small amount at the adhesive bond points and allow 30 seconds to air-dry, keeping eyes closed.

For professional use on individual eyelash extensions only. Do not use for self-application, clusters or strip lashes.
