Black Magic Tumbler Straw Charm

Does This Fit My Tumbler?

Great question — and we want to make sure you get the perfect fit before you order! Here's everything you need to know about compatibility for our tumbler handle charms and straw charms & baubles.

🧡 Tumbler Handle Charms

Our handle charms are designed to wrap around and dangle from your tumbler's handle. Each bracelet features a lobster clasp closure for easy on-and-off styling.

Compatible with:

• Most standard tumbler handles (round or oval cross-section)
• Handled cups in 20 oz, 30 oz, and 40 oz sizes
• Most handled mugs, travel cups, and other handled drinkware

How to check your handle:

1. Wrap a flexible measuring tape (or a piece of string) around your handle at its widest point.
2. If you used string, measure it against a ruler.
3. A circumference of approximately 3–5 inches (7.5–13 cm) fits our standard handle bracelet sizing.

Not compatible with:

• Handleless tumblers (straight-sided cups with no handle)
• Handles with very wide or irregular cross-sections outside the range above

🥤 Tumbler Straw Charms & Baubles

Our straw charms are made to slide onto or clip near your straw or lid. We offer three attachment styles — check the individual product listing to see which style(s) are available:

• 10mm Straw Topper — slides onto most standard reusable straws (10mm diameter). A plastic straw adapter is included with bauble-style charms.
• Flip Straw Topper — designed for flip-top tumbler lids with a built-in straw.
• Lobster Clasp / Bag Charm — clips onto a tumbler loop, handle, bag, tote, backpack, or keychain.

Compatible with:

• Most 30 oz and 40 oz tumblers with a standard reusable straw
• Tumblers with flip-top lids (flip straw style)
• Any bag, keychain, or tote (lobster clasp style)

Not compatible with:

• Straws narrower or wider than 10mm (for standard straw topper style)
• Tumblers with no straw opening or sealed lids

How to check your straw diameter:

1. Remove your straw from your tumbler.
2. Measure across the opening (the outer diameter) with a ruler.
3. If it measures approximately 10mm (about 3/8 inch), our standard straw charms will fit.
