StopTopps fits Solo cup-sized openings and smaller — red cups, plastic tumblers, canned drinks, pint glasses, and most standard party cups you'll encounter at bars and events.

Yes — that's the whole point. Every StopTopp has a pre-cut straw opening. Insert any standard straw and it creates a tight seal around it. You can sip comfortably without ever removing the lid.

Yes. StopTopps are made from recyclable materials. We care deeply about the planet as much as we care about your safety — that's a standard we hold ourselves to.

StopTopps creates a physical barrier that makes tampering more difficult and more visible. It is not a guarantee of safety. Think of it as an added layer — not a full solution. Always stay aware.

Most customers go with the 250 Pack — especially if you plan to share with friends, stock a dorm, or use them regularly. The cost per sticker drops dramatically. It's our most popular bundle by a wide margin.

Orders placed before 2PM ship the same day. Standard shipping is 3–5 business days. Free shipping is included on every single order — no minimum required.

Absolutely — this is exactly what most people do. The 250 and 500 packs are perfect for splitting between a group, sorority, dorm floor, or event crew. Everyone gets plenty and the cost becomes almost nothing per sticker.
