The age number is the real difference

Both packs are Blue Glitz holographic assorted table confetti in a 14g / 0.5 oz single pack, made from plastic and foil. The only functional difference is the age on the shapes: 18 or 21. That makes this a simple decision if you are decorating one milestone table, and a quantity question if you are covering both ages at the same event.

Because the supplied records do not include shape dimensions, piece counts or a full list of the assorted shapes, treat the 14g weight as your only confirmed quantity guide. If you need to know exactly how many 18s or 21s are in a pack, ask before ordering rather than guessing from the weight.

18th vs 21st Blue Glitz confetti at a glance

  • Blue Glitz 18th Birthday Holographic Assorted Table Confetti 14g: Age 18 shapes, 14g / 0.5 oz, plastic and foil, sold as a single pack. Catalog price USD 0.71 against a comparison price of USD 0.99.
  • Blue Glitz 21st Birthday Holographic Assorted Table Confetti 14g: Age 21 shapes, 14g / 0.5 oz, plastic and foil, sold as a single pack. Catalog price USD 0.63 against a comparison price of USD 0.99.
  • What stays the same: Holographic shimmer, assorted shapes, the same pack weight and the same material mix. Neither record confirms piece counts or shape sizes.
  • What changes: The age number on the confetti and the current catalog price. At the time of writing the 21st pack is listed lower than the 18th pack, but check the live price before you rely on that.

Where each pack works best on the table

The supplied product details list three uses for both packs: sprinkling on tables, adding to cards and tucking into gift bags. Use those as your placement guide rather than inventing a scatter pattern.

  • One clear milestone: Choose the pack that matches the age you are celebrating. An 18th table with 21 shapes, or the reverse, creates a mismatch guests will notice.
  • Two ages at one party: Buy one of each and keep them in separate bowls or zones so the 18s and 21s do not mix into a confusing scatter.
  • Cards and gift bags: Both packs are described for use in cards and gift bags, so a single 14g pack can be split between table scatter and a few envelopes.
  • Large tables: The records give weight but not piece count. If you are covering a long buffet or many guest tables, order extra singles rather than assuming one 14g pack spreads far.

The trade-offs the catalog does not settle

Neither record confirms the size of the individual shapes, the exact mix of assorted shapes, or whether the holographic finish is on one side or both. Those details matter if you are matching the confetti to printed invitations or a specific table palette, so ask before ordering if they are critical to your plan.

The material is listed as plastic and foil. That is useful for indoor table scatter and card inserts, but the supplied information does not include outdoor use, recycling or disposal guidance. Do not assume this confetti is suitable for outdoor venues or compostable settings without checking with the seller.

There is also no safety or age-suitability information in the supplied records. Keep small confetti pieces away from young children and pets as a sensible precaution, and treat any specific warning as unconfirmed until you see it on the packaging.
