1. What Is This Business?
You host a hands-on party where guests build their own custom phone case using resin and charms. Everyone leaves with a one-of-a-kind case they made themselves — and because the results look so good, guests post them online, which is exactly how your next booking finds you. It's part craft night, part party experience, and it works for everything from birthdays to bachelorettes.
2. Startup Costs & Budget
You can get your first event fully stocked for around $150–$250, depending on how many bezel cases and charm varieties you start with. Since your per-guest supply cost is only $5–$8 in bulk, this pays for itself in your very first party.
UV resin + UV light kit (squeezable tube resin, comes packaged together): ~$40🔗UV resin and light kit
Assorted charms (bulk pack): ~$30
Blank bezel phone cases, assorted models: ~$60🔗bezel phone case iPhone 17 (blue)🔗bezel phone case iPhone 17 (white)
Tweezers for charm placement, mixing cups, stir sticks: ~$15🔗resin tweezers
Disposable tablecloths and wipes (already have on hand for most moms): ~$10
Estimated Total Startup Cost: $150–$250
3. Supply List & Where to Buy
UV resin — Comes in an easy squeezable tube, usually packaged together with a UV light, which cures fast and matters when you're running a group through a timed event.🔗UV resin and light kit
Charms — Bulk charm mixes (flowers, shells, initials, mini beads) are cheapest on Amazon or at craft stores like Michaels when they run their sales.
Bezel cases — Buy a range of the most common phone models in bulk. I always recommend collecting everyone's phone model ahead of time so you're not guessing.🔗bezel phone case iPhone 17 (blue)🔗bezel phone case iPhone 17 (white)
Tweezers — A must for precise charm placement in the resin before it cures.🔗resin tweezers
Take-home kits — Pre-portion resin, a mini charm assortment, and a case into a small bag or box. Offer two versions: one with a mini UV light included, and a lower-priced one without, since guests may already have their own light after the party.🔗kit packaging
Table setup — Disposable tablecloths and wipes from Dollar Tree or Sam's Club keep cleanup fast between guests.
My biggest money-saver is buying charms and resin in bulk packs rather than small craft-store bottles — the per-unit cost drops fast once you're buying for a group of 10 instead of one project at a time.
4. Pricing Strategy
At $5–$8 in supplies per guest and a $35–$50 charge per person, you're looking at a very healthy margin even before you factor in that you're also getting paid for your time running the event.
$35 per guest: A great entry price for casual groups like girls' nights, where guests are price-sensitive but still want the full experience.
$45–$50 per guest: Fits birthday parties, bachelorettes, and corporate events where there's a built-in budget and an expectation of a more elevated experience.
Take-home kits: Price the version with the UV light at $25–$30, and the resin-and-charms-only version (for guests who already have a light) at $15–$20. Both are add-on sales — pure profit since guests are already in a buying mood by the end of the party.
A Simple Rule of Thumb
Charge at least 5–6x your per-guest supply cost. That covers materials, your setup and cleanup time, and the experience itself — not just the raw ingredients.
5. How to Find Customers
Your Best First Customers
Birthday parties: Moms are always looking for a party idea that doesn't feel like the same bounce-house setup everyone else does.
Girls' nights: Friend groups looking for a fun, low-key evening that still feels like an event.
Bachelorettes: A creative activity that photographs beautifully and gives the group something to do together.
Corporate team events: Companies are often looking for team-building activities with a real takeaway, and they typically have more budget to spend per person.
Where to Advertise
Post your finished cases on Instagram and TikTok — the visual "wow" factor of a finished resin case does a lot of the selling for you.
Share in local mom Facebook groups and Nextdoor, especially around birthday season.
Reach out directly to local HR or office managers about corporate team-building bookings.
Ask every guest to tag you when they post their case — this is genuinely how most bookings for this kind of business happen.
6. Step-by-Step Launch Guide
Order your starter supplies — resin, charms, and a range of common bezel case sizes.🔗UV resin and light kit
Practice a few cases yourself — get comfortable with resin ratios and cure times before your first paid event.
Set your package details — decide your per-guest price, group size, and event length (2–3 hours works well for a group of 10).
Create a simple booking flow — a short form or direct message template asking for date, guest count, and each guest's phone model.
Design a flyer or Instagram post showing your best finished cases to advertise your first event.
Book your first event — offer a friend or family member a discounted "practice run" to build your portfolio of photos.
Collect phone models in advance for every guest, or ask them to bring their own bezel case if you don't have their model on hand.
Run the event — set up stations, walk guests through the resin and charm process, and let the cases cure while you chat and take photos.
Offer take-home kits at the end of the event while guests are still excited about what they made — let them choose the version with the UV light or the lighter-priced resin-and-charms-only option.
Follow up — tag guests in your post-event photos and ask them to share their own so your next booking can find you.
7. Income Potential
Starter (1 event a month, 10 guests at $35): 10 × $35 = $350 → ~$350/month
Growing (2 events a month, 10 guests at $45, plus kits): 2 × (10 × $45 + 5 kits × $25) = $1,150 → ~$1,150/month
Full Roster (4 events a month, 10 guests at $50, plus kits): 4 × (10 × $50 + 5 kits × $25) = $2,500 → ~$2,500/month
Weekends are the natural sweet spot for this business, so even a couple of parties a month can add up to solid supplemental income — and corporate bookings can push your per-event total even higher.
8. You've Got This
You already have the concept people want — a creative, photogenic experience they can't stop posting about. Start with one event, get those first photos, and let your guests do the advertising for you. You've got everything you need to make this real.
