In this review of the Tondiamo 100 Sets 58 mm button maker keychains kit, the bottom line is simple: it is a practical bulk supply for crafters who want a portable, repeatable way to make custom keychain badges. The package includes 100 metal shells, 100 clear films, 100 back covers and 100 keychains plus a ring, which makes it easy to produce a lot of finished pieces without frequent restocking. For anyone running workshops, class activities, or creating small gifts, the kit's quantity and familiar 58 mm size are the single biggest reasons to consider it.

Key Features

• Complete bulk set: Includes 100 metal shells, films, back covers and keychains so projects can be produced in quantity without running out quickly.
• Standard 58 mm size: The 2.28 in diameter is a common badge size that fits most badge maker molds and is easy to handle for small hands.
• Tinplate and PVC construction: Metal shells with a clear PVC cover give a smooth, bright finish that protects prints and holds up on keys or bags.
• Easy to assemble: Designed for use with a manual badge maker, the parts press together quickly to yield a neat finished keychain.
• Portable and versatile: Finished keychains are slim and pocket-friendly, suitable for backpacks, key rings, event giveaways or rewards.

Who It's For

The kit is aimed at hobbyists, teachers and small organizers who run DIY sessions, parties or classroom activities and need a dependable supply of matching keychain badges. Because it comes with 100 complete sets, it is especially useful where multiple participants each make or receive their own badge.

It is less suitable for someone who only wants a handful of samples or who needs specialty shapes or materials; this package is best when quantity and the standard 58 mm round format are desired.
