Topbooc Regular-Mouth Mason Jar Canning Lids 150-Pack (70mm) — Split-Type Tinplate with Airtight Sealing Ring

Topbooc regular-mouth split canning lids are food-grade tinplate replacement lids designed to create airtight seals for standard Ball and Kerr mason jars.

These 150-count metal canning lids fit most regular-mouth jars (70mm / 2.76 inches) and are made to handle temperature changes while keeping contents secure. They are the split-type design — lids only, without bands — and include an internal sealing ring to lock out air and moisture for preserves, dry storage, dressings, and more. Built from tinplate, they are reusable, compatible with refrigerators and dishwashers, and suitable for everyday kitchen use where a reliable, low-cost lid is needed.

How do these lids perform during home canning and storage?

The internal rubberized sealing ring provides a tight closure that reduces the risk of leaks and contamination after sealing. While designed for everyday cold storage and short-term sealing, they are compatible with many household canning routines.

• Tight internal gasket for airtight closure
• Compatible with most regular-mouth Ball and Kerr jars (70mm)
• Suitable for preserving condiments, dry goods, and refrigerated items

Are Topbooc lids reusable and heat-safe?

Made from tinplate, these lids tolerate a range of temperatures and can be reused multiple times if the sealing ring remains intact. They are safe for refrigerator storage and can withstand dishwasher cycles; avoid prolonged high-heat exposure if the seal shows wear.

• Tinplate construction resists corrosion and temperature shifts
• Dishwasher-safe on the top rack for convenient cleaning
• Reusable as long as the sealing ring remains undamaged

What does “split-type” mean and how do I use these lids without bands?

Split-type indicates the product includes only the flat lid portions (not the threaded bands). The lids work with standard screw bands to secure them during sealing; they also pair with silicone fermentation accessories and sprouting lids when paired with a band.

• Lids alone — bands sold separately — for flexible replacement options
• Screw-thread on jars increases grip for easier opening with a band
• Compatible with home fermentation and sprouting add-ons when used with a band

How many lids are included and which jar sizes are supported?

This set contains 150 regular-mouth lids sized at 70mm (2.76 inches), made to fit most standard regular-mouth mason jars from common brands. It’s an economical option for batch canning, craft projects, or restocking pantry supplies.

• 150 replacement lids per pack for frequent use
• Designed for regular-mouth jars (70mm / 2.76 inches)
• Ideal for bulk projects or keeping spare lids on hand

Who is this for: Home cooks, small-batch makers, and anyone who needs an affordable supply of dependable regular-mouth mason jar lids will find this Topbooc set useful. It’s tailored for people who already own standard Ball or Kerr jars and want a reliable replacement lid supply for food storage, refrigerated preserves, fermentation projects, or pantry organization. If you need both lids and bands, remember bands are not included in this pack.
