Do beadable pen beads have a vertical or side hole?

For pens you need a vertical hole so the design faces the user; side-hole beads are meant for bracelets and phone chains. Several of our stock designs are listed specifically as vertical-hole, and we confirm hole direction per SKU before you pay.

What is the minimum order for pen beads?

One bag. Nineteen of the 22 stock designs pack 100pcs per bag, which is roughly 100 finished pens — small enough to test a theme, large enough that per-unit freight stops hurting.

Can you make a custom bead shape?

Yes, but it is quoted per project rather than from stock, because a new shape means a new mould. Flexible moulds yield roughly 25 to 100 castings before fine detail degrades, so tooling is a real cost line rather than a one-off artwork fee.

What bead size should a first range use?

Weight it toward the 20 to 25 mm band — visible in listing photos but still comfortable to hold. Add 30 mm-plus statement beads only for gift and seasonal lines, and keep a small spacer design in stock to balance the barrel.

Beadable Pen Beads: Hole Size, Lots and What Actually Sells

Updated July 2026 · by the Qula Craft Sourcing Team — the people who quote and pack these lines every week.

Short answer: beadable pen beads are resin focal beads with a hole wide enough to slide onto a standard pen blank. Our line runs 22 stock designs, almost all packed 100pcs per bag with a 1-bag minimum, in sizes from roughly 12 mm up to 37 mm. Buy by theme, not by single design — a pen needs one focal bead plus spacers, so a seller who stocks 6–8 themes outsells one who stocks 30 random shapes.

1. The hole is the spec that decides everything

Nothing else matters if the bead will not go on the blank. Two things go wrong in practice: the hole is too narrow for the pen barrel, or the hole runs the wrong way through the bead. Both look identical in a photo.

Vertical hole (through the top and bottom) is what a beadable pen needs — the bead sits upright and faces the user. Side hole beads are for bracelets and phone chains; put one on a pen and the design lies sideways. Several of our stock designs are explicitly listed as vertical-hole for this reason, and a handful are dual-purpose. When you request a quote, say “for pens” and we confirm the hole direction per SKU before you pay.

Ask for the hole diameter in millimetres, not “large hole”. Pen blanks vary by supplier, so the safe move on a first order is to post us one blank, or a photo with a ruler against the barrel.

2. Sizes: what a 12 mm bead and a 37 mm bead each do

Size band (from our stock line)	Role on the pen	Typical use
~12–15 mm	Spacer / accent	Sits either side of the focal bead; keeps the barrel balanced
~20–25 mm	Everyday focal	The workhorse size — visible in a photo, still comfortable to hold
~30–37 mm	Statement focal	Gift and novelty pens; photographs well but adds weight at the top

Our stock designs land across this whole band — for example a 15×20 mm candy-corn bead, a 20×12 mm cat bead, a 23 mm curly-dog bead and a 25×37 mm swan. If you are building a first range, weight it toward the middle band and add statement pieces only for seasonal gifting.

3. The 100pcs lot, and why it is the right unit

Nineteen of our 22 designs pack 100pcs per bag, and the minimum is one bag. That is deliberate: a bag of 100 focal beads is roughly 100 finished pens, which is a realistic first production run for a market stall, an Etsy shop or a school fundraiser. It is small enough to test a theme and large enough that the per-unit freight stops hurting.

Do the arithmetic before you commit to a design. If a bag lands at, say, $3–$7 per 100pcs depending on design and quantity band, your bead cost per pen is a few cents — the blank, the packaging and your labour will each cost more than the bead. That is why buying the right design matters more than shaving the bead price.

4. Resin, and the one physical limit worth knowing

Twenty-one of the 22 designs are cast resin. Resin casting is well suited to exactly this kind of product — it is used for small-scale production of collectible toys, models and figures, which is essentially what a novelty focal bead is.

The limit to know: mixing the two resin parts causes an exothermic reaction, and the heat plus the aggressive compounds degrade the mould over time — a flexible mould typically yields between 25 and 100 castings before it starts losing fine detail. Two practical consequences for you:

Custom shapes carry a real tooling cost. A new design is not just artwork — it is a mould that wears out. That is why bespoke shapes are quoted per project while stock designs ship from one bag.
Fine detail drifts slightly between batches. On highly detailed designs, ask for a current-batch sample rather than relying on a listing photo shot from an early mould.

5. Resin or clay? They fail differently

Not every bead on the market is resin. The other common material is polymer clay, which is a PVC-based modelling material cured at roughly 129–135 °C. Both arrive as hard, finished pieces, but they behave differently once a customer is using the pen:

Cast resin takes sharper moulded detail and a glossier finish — better for faces, eyes and lettering.
Polymer clay pieces are usually built from canes, so patterns run through the body of the bead rather than sitting on the surface. Scuff a clay bead and the pattern is still there; scuff a painted resin bead and it shows.

For pens, where the bead is handled constantly, we stock resin for detail-led designs and treat clay as a pattern option. If a customer complains about wear, that distinction is usually the reason.

6. Build a theme, not a catalogue

The sellers who reorder fastest do not stock the most designs. They pick a lane and go deep enough that a customer can buy a matching set: animals, desserts, Christmas, ocean. Our stock line already clusters that way — cartoon bears, dogs, cats and corgis; cookies, cakes, chocolate and candy corn; starfish and ocean animals; penguins, trees and gift boxes for the holiday range.

A workable first order is 4–6 focal designs inside one theme plus one neutral spacer design. That is five to seven bags, it photographs as a collection rather than a jumble, and it leaves budget to reorder whatever sells through first instead of sitting on 20 slow designs.

Before you order: confirm hole direction (vertical for pens), send a photo of your pen blank with a ruler, and ask for a current-batch sample on any design where fine detail is the selling point.
